Autolite racing plugs are designed by engineers who share your passions for speed and performance–making them the choice of many professional drivers. When you race, everything that goes into your engine counts. There are restrictions on the temperatures at which spark plugs can be used: the lower limit is the self-cleaning temperature and the upper limit is the pre-ignition temperature.A spark plug only functions completely when its center electrode temperature is between these temperatures of about 500☌ and 950☌. Autolite platinums are one of the only plugs that worked well in my Ford. A damaged or worn spark plug, as well as faulty spark plug wires or coils, can cause cylinder. For this reason, Denso plugs do not last longer than NGK units, but they are better at producing powerful sparks.Īutolites are very good in many vehicles especially as a replacement for Motorcrafts. Autolite out, NGK in, drive, light clears and all is good. The electrode’s diameter in Denso plugs shrinks more than an NGK. The iridium used in them has a superior hardness. Which is better NGK or Denso Spark Plugs?ĭenso plugs are installed on almost every automobile model manufactured in Japan. Autolite Iridium XP spark plugs offer the same platinum ground electrode enhancement with the added benefit of fine wire iridium on the center electrode.

These spark plugs also feature a high nickel alloy side electrode to maintain a precise gap, and a full platinum tip to ensure virtually no gap erosion.ĭo not change the gap on platinum, iridium or twin tip spark plugs, as the fine electrodes may get damaged. Also, the spark plug gap should never exceed. What should the gap be on a brisk spark plug Excessive changing of the spark plug gap setting will result in weakening of the spark plug ground electrode and can lead to breakage. Car runs better with the autolites and the ngk will start to slowly load up.Īutolite Platinum Spark Plugs feature a center wire platinum firing tip for reduced gap erosion, fewer misfires, better performance, and more durability. Additionally, the spark plug gap and point gap in all models were 0.035 inch and 0.019 inch, respectively. The quality of ngk is better, but I have one car that just likes autolites better, same gap & heat range. A spark-plug gap gauge both measures and adjusts the gap and is inexpensive and simple to use. The Spark-Plug Gap If the gap is too small, the spark will likely be too weak and cause the engine to run poorly or with poor efficiency. What happens if the gap is too small on a spark plug? Gapping has always been the job of the installer. Because of the many gap sizes required, no one offers spark plugs properly gapped for every application. Q Are these calibrated?ĭo Autolite spark plugs need to be gapped?Īutolite® and all spark plug manufacturers offer spark plugs pre-gapped in the most popular gap sizes. 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.This Autolite Copper Resistor Spark Plug – Part # 25 is an exact fit for your 1988 Ford F-150 Pickup 5.0L 302CI. 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?
