Tis the season for tune-ups, my friends! Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Spark plugs are a popular item to change, and it is important to know what a good spark plug vs. a bad one looks like.There are tons of different types of spark plugs (iridium, platinum, standard, pre-gapped, 4 grounded etc.,) but there still are some telltale visual signs that tell you of a bad spark plug (or a poorly running cylinder). Adjusting the distance between the two electrodes is called gapping your spark plugs. $15.99. 5 years ago If you have good air/fuel mixture in your cylinder the spark obviously still ignites it from any angle if your engine is functioning properly. Assuming the preset gap is too small, wrap one side of a pair of needle nose pliers with electrical tape to prevent damage to the spark plug when gapping. HOW SIDE GAPPING WORKS: 1 closer gap allows for easier ignition 2 2 angled surfaces allows the ignited spark The spark plug is the life source in an engine. He said his mpg went up 6mpg and said it seemed a lot smoother. You need to be careful not to hit the center electrode or the porcelain. Keeping it dry CREATES a much bigger, nastier scar and delays the healing process by at least 40%. Share it with us! Gap new as well as old spark plugs… The gap should be adjusted by only moving the ground electrode. Acetone is much more expensive than gasoline and may be much more harmful to your car and pollution. Are you really so desperate for 1% increase in horsepower (maybe with a plug) in your car which you can't detect anyway unless on a drag strip and at full throttle and worse MPG? 12 years ago Cutting the ground electrode gives you a smaller area for the spark to jump to eliminating reliability. Using my trusty microscope, I can see the center electrodes were still tipped with iridium. ), and changed the CR9E plugs for nonresistor C9E spark plugs (5 Kohms) and now it runs great you can fell the bike has more power and starts up under all conditions. The gap between the center and side electrodes of a spark plug must be an exact distance; otherwise, your plugs don’t fire efficiently. Reply It's more than a 100 years later and it's still being used....So There! True surface discharge or surface gap spark plugs have no side electrode, instead utilizing the entire face of the plug shell as a ground to ignite. The center alloys with iridium, and a special U-shaped groove is made on the sides, but not alloyed. Reply 5oz to 10 gallons. There have been plenty of technologies that have gone basically unnoticed by the general population simply because they are unpopular or don't fit into the "American Way"(basically quick/easy/cheap). Parts like the XP-104 Iridium spark plugs are also a good option when replacing the spark plugs. Many manufacturers offer plugs deemed racing plugs that are side gapped but at inflated costs. Not necessarily, commercials(especially those showcased during the superbowl) are dictated by trends and marketing plans. Fine iridium tip ensures high durability and a consistently stable spark; Trivalent metal plating for superior anti-corrosion and anti-seizing properties http://www.sccoia.org/articles/top-fuel-dragster-f.... Don't you think an engineer might know a bit more than the average home "bench racer"? Always use a special spark plug gapping tool to change the gap. Every car manufacturer uses different spark gaps and levels of spark energy. I don't know, maybe it will clean your engine and plug but may harm your oxygen sensor or catalytic converter or clean the oil off your cylinder walls removing the lubrication and causing more wear. 6 years ago, People back in the day also thought the earth was flat until someone came up with some hard evidence to disprove that ;-) Lots of "experts" do lots of things in lots of fields for long periods of time that are complete BS. Some octane boosters say they can harm engines and other parts but give more power. The majority of these plugs come pre-gapped from the factory. Running the right plug optimizes the spark. It appears the coil has to work harder as the gap increases. In my opinion, the spark plugs are the … https://www.hotrod.com/articles/does-side-gapping-spark-plugs-work/, (You must log in or sign up to reply here.). Wrap Pliers with Tape Grip the ground electrode with the needle nose pliers between where the ground electrode is fused to the spark plug thread and the center electrode. While in the East, Japan and China--among others--have a more productive view. Free shipping . Many people don't study the different types of plugs and may be using the wrong type, especially if they have made modifications. Free shipping . My reference to the Superbowl was, of course, a metaphor. I first heard of "Side Gapping" spark plugs here on this forum, it made sense to me so I tried it on a fresh set of plugs. Since the fuel in the combustion chambers does not ignite completely, you will notice a decrease in gas mileage. Using a dremel with a cutoff wheel or a hacksaw you will need to cut the ground electrode even with the edge of the center electrode. The spark can only go from corner to corner, rather than having the ability to use the entire flat surfaces on both sides to find the best path when carbon deposits build up and hinder spark. 12 years ago However, when dealing with a modified engine, you should adjust the NGK iridium spark plugs as needed. $16.80. The American Way can be very simply stated: you're as good as the next guy, and you can take your shot the same as anybody else. Many manufacturers offer plugs deemed racing plugs that are side gapped but at inflated costs. And bragging about it in Superbowl ads? Responding to a comment: what might acetone do to your fuel lines and plastic parts in your engine? The old plugs had 38552 miles on them. Taken from the link below: "A racing plug differs from a street plug typically by the heat range and expectation of durability. HOW SIDE GAPPING WORKS: The closer gap (1-Yellow) allows for easier ignition while the angled surfaces (2-orange) allow the ignited spark to grow in size to exceed that of normally shaped plugs. Check out the plugs on this page for an extreme version of this plug mod. I changed the gap back to factory specs. The spark will always choose the path of least resistance, and contrary to what some people believe, plugs with multiple side electrodes don't produce multiple sparks. Always use a special spark plug gapping tool to change the gap. Indexing the plug is having the open end of the plug facing the intake valve. Please take a moment and Register today. Free shipping . $19.76. I like consistency. It should be such that you hold the spark plug with the electrodes facing the floor. While a coin-style tool can be used in a pinch, albeit cautiously, it is far too easy to damage the iridium or platinum metals, which decreases the lifespan of the plug. You need a feeler gauge to gap your spark plugs properly. $17.28. A Top Fuel racer is using a MUCH more powerful spark, completely different fuel and may use 11.2 gallons per second which is the same as a 747 plane. Not gapping plugs is hard to get used to, but you should not gap Iridium and Platinum tipped spark plugs. Spark plugs receive electrical charge from the distributor or coil to create a spark that causes combustion. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs. Absolutely no Rf inteference that all a joke to reduce emissions. $15.99. If the spark plugs are defective, the gap between the side and center electrode is often too large or too small. With the side gapped plug the spark is now un-shrouded and is more exposed to the fuel/air mix. If you have 200hp x 0.01 = 2hp max under perfect conditions! Running too cool a plug causes fouling, which inhibits a good spark. This may be for combustion chamber design as in the case of a rotary engine, or a surface gap design as used in leaner air/fuel ratio’s on industrial engines. If they’re within .002 and you don’t have the gapping pliers (few people do but they’re inexpensive) then I would leave them alone due to the cost of Iridium plugs. I also have to note if you side gap your plugs it's best to index them also. But...if it were that easy to increase mileage and horsepower...wouldn't the manufacturers be doing it? On a more basic level, the media--both print and electronic--have long since fallen into bash-America mode. To do this you will need to find the manufactures setting for your vehicle and reduce that by 0.010". The air-fuel mixture has a much higher resistance than the metal of the electrodes so making the gap larger makes the resistance that much more. You want the ground electrode to end where the spark plug's center piece begins. Ever try 100% pure acetone? Use caution increasing spark plug gaps. Iridium and Platinum tipped spark plugs Do not gap Do not clean Do not remove The only “maintenance” is replacement. Gapping Methods. If this step is not done the burrs could heat up until they glow red hot causing detonation. Look closely at the plug electrodes in the cylinder head picture I included. After the burrs are removed you will want to use some alcohol or starting fluid to thoroughly clean the plug to make sure there are no metal filings left. To learn more, please google basic electrical theory and how spark plugs work. Free shipping . 6 years ago By doing it yourself you can use a cheap .99 cent plug to save money and increase horsepower. 2. Their fuel economy can be 40 gallon per mile! Genuine Nissan Value Advantage Hybrid 20" Side Mount Wiper Blade. Side-gapping or cutting back the ground electrode exposes more of the spark to the fuel mixture. This means that the smaller area you mentioned actually makes for a better spark. Did you make this project? Example: manufacture setting 0.035" - 0.010" = 0.025". Iridium plugs wear faster than I thought. A pair of spark plug gapping pliers is by far the safest way to gap plugs, no matter if they’re Iridium, Platinum, or copper core. In this case, you do not necessarily have to buy new plugs. But we don't want to keep such things to ourselves, we want Europeans to have them too. For modern fine-wire spark plugs, you should not measure the gap unless instructed by the manufacturer because you could damage the center electrode. They want to be us. Didn't mean to change the subject. I did this on a Ford Ranger 3.0. Running too hot a plug may cause pinging, or just melt the spark plug. Next you will need to use a file to remove any burrs left from cutting the ground electrode. Side gapping spark plugs has been use in racing for years to increase horsepower by unshrouding the spark thus allowing the flame created to propagate faster resulting in a more complete burning of the fuel/air mix. The Ethanol they put in our fuels is more harmful to our cars, especially older ones which were never meant to run it, which is why Ethanol is limited to 10-15%, and why there are Flex Fuel E85 (85% gas/15%Ethanol) designed vehicles. I think you may have misread the article you cited. https://www.hotrod.com/articles/does-side-gapping-spark-plugs-work "Spark plugs with fine wire center and/or ground electrodes operate better for two reasons. the flame created will now be able to spread faster resulting in a more efficient burn before the exhaust valve opens. 4 years ago. Welcome to our site! They consist of a terminal at one end that receives the charge, and a center and ground electrode that arc to create a spark. on Introduction. 4. Your HP is measured at full throttle, worst MPG and "perfect" conditions, new and at sea level. Just increasing the gap will not make the spark better; it will actually weaken it. If adjusting the gap on fine wire or precious metal plugs such as platinum or iridium, be very careful not to apply any pressure or prying force to the fine wire center electrode or insulator as they can be damaged. But as the "chosen" electrode wears (from more use than the others), its gap will widen, causing one of the unused (or less used) electrodes to become the "chosen" one by default. There is more concern for pollution than your power output and life of your engine. Reply But the view that "they" (any they) are better than America is mistaken. But, it is still a good idea to inspect the new spark plugs for damage or defects. If anything, increasing the gap would theoretically increase the speed of the burn because you're igniting more fuel initially vs a shorter spark. Do not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged. An air intake and exhaust upgrade is a more realistic upgrade with much higher gains. They were installed with a gap of .028". Want to try it on my car to see if I notice a difference. Spark plugs are mighty little workers. Reply Side gapping spark plugs has been use in racing for years to increase horsepower by unshrouding the spark thus allowing the flame created to propagate faster resulting in a more complete burning of the fuel/air mix. The second reason is smaller center and ground electrodes reduce quenching." I'm a Dr - there are so many medical myths that Drs and nurses get passed on and will never stop - they're complete BS and have no fact basis but they still do it and it gets passed on!! Lastly, I googled "Top Fuel spark plug size comparison" and could not really find any major differences compared to your standard engine. Thought it was BS so I tried it on my wife's RDX and couldn't believe the difference. While spark plug gap does not have a direct effect on timing, excessive gap in a power adder application can easily cause engine misfire. That's another thing about the American way: you can have your opinion, you can state it as loudly as you like, and all Americans band together to protect your right to do so. Speaking of different fuels racers use and additives like the guy who mentioned acetone, the cost of fuel is directly related to your MPG cost everyone is talking about. Some engine designs require the spark plugs have the ground electrode placed to the side of the center electrode rather than below as on a traditional plug. One of them is platinum, the other is iridium. As you can tell by now, the 5.3 engine combustion chamber gets super hot, so you are going to want spark plugs made from iridium because of the super heat-resistant capabilities. Meaning a manufacturer who comes up with a better way tends to shout the news from rooftops (also metaphorically). As ZakC2 mentioned, dirty, fouled plugs may not be as efficient having a weaker spark. The only thing side gapping will do is change WHERE the burn begins - not how much or how fast or how completely the mix burns. By doing it yourself you can use a cheap .99 cent plug to save money and increase horsepower. Free shipping . Calculate 0.01 of your power and MPG. Newer plugs are proven to burn better because they are producing a bigger (fatter), hotter spark. First, a smaller center electrode requires less voltage to jump the gap. Spark plugs usually have a build-up of white soot on the electrode, which can reduce the size of the gap. Side gapping has been used going back to the First Days of Indy Racing. Ever read on an ER direction sheet to keep your stitches "clean and dry" - absolute worst thing to do for any wound!! It seemed to run OK but within a month the coil went bad and had to be replaced. Also a buddy of mine tried it on his Dodge pickup with I think it's a 5.7 hemi. Our gas prices are cheap compared to other fuels, you pay more for Hersheys syrup & laundry detergent than gas. Iridium’s extremely high melting point is perfectly suited to today’s high-temperature engines, delivering outstanding acceleration, fuel efficiency and durability. Then using a feeler gauge of the correct thickness insert it at a 45* angle to check and adjust as necessary until the gap is correctly set. $22.95. Compare the two ethical stances, and decide which is better. Thus the gap remains constant through the plugs entire life. What is acetone usually used for, nail polish remover, etc? There is just too much to say about what to do to your spark plugs. Can this be applied in a motorcycle sir ? Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. You would have to increase the power to the plug in order for the spark to be able to cross the increased gap. Set 4pcs 22401-JD01B Denso FXE20HR11 Iridium Spark Plug For Nissan Altima Sentra. 6pcs Laser Iridium Spark Plugs PLFR5A11 22401-5M015 for Infiniti FX35 G35 Nissan. Had it in the dealer and asked them to check the fuel system while it was in there and they said there was nothing wrong with it. I would think a side gap would wear the smaller corner of the spark plug electrode faster needing more adjustment and replacement more often. The Grandson of 1st Indy Winner in 1911 Ray Harroun (Bill) use to come to the Circle Burner Motorcycle and Sprint Car Races locally. Genuine Nissan Value Advantage Hybrid 20" Side Mount Wiper Blade. The top fuel dragsters have much larger cylinders and 8000 hp (1000hp per cylinder) yet the spark plugs are not that different but use 2 plugs per cylinder and every other component is bigger and better, like the ignition/spark size. Just throwin that in to see if anybody's ever tried that?
