![]() ![]() Clearly there are people that want to make a small investment to better the health of their vehicle and not have to worry about having to possibly buy twice. The price would be a little cheaper if I wasn't shipping 120 plugs a week. However if you don't want to risk it you can pay me for my time, and get a plug that is guaranteed to perform as it should. So, you can absolutely gap your own plugs and I tell people that all the time. Boost was actually lower, and timing/fuel was the same. The car went from 294whp to 323whp without even changing the tune. He grabbed a set of plugs off the shelf, gapped them with his gapping tool, and installed. NGK IX Iridium Spark Plugs - pre-gapped Fine Iridium tip ensures high durability and a consistently stable spark Iridium alloy has an extremely high melting. ![]() I asked what plugs were in it and he said stock. plain normal plugs usually dont and need to be gapped per the specs of the vehicle platinum/iridium types usually do but always visually inspect them for damage anyway before installing them. The power numbers were off, but the car was running smooth and pulling fine. depends on which type of spark plugs you buy/need. Not to long ago I was doing live remote dyno tuning for a shop in Ohio. DO NOT ADJUST THE GAP ON IRIDIUM PLUGS IF YOU CAN AVOID IT It is extremely easy to crack the iridium coating on the electrode and ruin the plug. All plugs should be checked prior to installation. People don't understand the importance of having a properly gapped quality plug in these cars. All the above plugs are pre-gapped to roughly 0.030' with the exception of the ones listed with larger gaps. If the plug starts igniting anywhere BUT the channel in the ground electrode you get weak spark and can cause spark blowout. The channel on the bottom side of the ground electrode is raw - no plating, so when you create more raw spots on the ground electrode you are making it hard for the plug to generate a straight spark between the gap. When you opened it back up to re-gap you marred the metal and removed some of the plating. Which won't cause a dead plug but will cause inconsistent spark as it will possibly be igniting off the side of the ground electrode. If you make the gap too tight and you have to open it back up you mar the ground electrode. If you knock it off you have a dead plug. The manufacturer of your vehicle, the company that produced the aftermarket products you’ve used, and/or your service technician are all additional sources of gapping information if you’ve modified your vehicle.Actually the damage is actually from gapping, most customer knock the iridium welded tip off because it is extremely brittle and soft. If you have any questions, please contact the NGK Spark Plugs Tech Staff > However, when you add a high power ignition system (such as those offered by MSD, Crane, Nology) you can open the gap from. As an example, when you raise compression or add forced induction (a turbo system, nitrous or supercharger kit) you must reduce the gap (about. The gap should be adjusted by only moving the ground electrode.Īnother consideration that should be taken into account is the extent of any modifications that you may have made to the engine. 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. It is always best to check the gap against the manufacturer’s specifications. The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear. Although the NGK factory will set the gap to a preselected setting, this may not be the right gap for your particular engine. A spark plug part number might fit hundreds of different engines from many different manufacturers. ![]() DO I NEED TO SET THE “GAP” WHEN INSTALLING A NEW SET OF PLUGS? ![]()
