Description:
DENSOs Iridium Long Life spark plug is fast becoming the standard for todays high-tech engines. Designed for durabilty under the most extreme conditions, DENS0s patented indium alloy is six times harder and eight times stranger than conventional platinum and can handle temperatures In excess of 4,000F.
Closely related to platinum and exhibiting even tougher qualities, the rare metal iridium is an ideal material for spark plugs. The DENSO Iridium Long Life plug was specifically designed for long service life and consistent performance in the latest, most advanced production cars. A fine-wire, 0.7mm iridium center electrode is 360-degree laser welded in place using an exclusive DENSO process, then matched to a platinum ground electrode. This pair of precision-formed, premium-metal electrodes dramatically extend the plug's useful life. The DENSO Iridium Long Life plug has been selected as original equipment on many of the world's top cars, including those from GM, Toyota, Honda, and Mitsubishi. There's a simple reason for that: these manufacturers needed the best.

Q: How do you install spark plugs?
A: Spark plugs are installed by using a spark plug socket. Simply remove the spark plug wires and unbolt the plugs. Replace and gap the new plugs and you should be set.
Q: What are spark plugs? Why buy spark plugs?
A: Spark plugs create a spark in the combustion chamber of the engine, igniting the fuel and air mixture and getting the engine running. When you're running a higher horsepower motor, spark plugs play a big role. A colder heat range plug (which is what more aftermarket spark plugs are) has less insulation; it cools off faster between firing and the introduction of a fresh charge of the air/fuel mixture. A hot plug can ignite the air/fuel mixture before the plug actually fires. This is called pre-ignition, a form of detonation, and can destroy a motor. When upgrading the power of your vehicle, make sure to look into a colder range spark plug.
Q: Do spark plugs come in sets of 4?
A: Spark plugs are sold individually (unless otherwise noted) and should be replaced all at the same time.
