Designed to ignite the air/fuel mixture within the combustion chamber, a spark plug has to withstand the high temperature and combustion pressure within the engine. If everything operates properly, the engine runs efficiently providing optimal performance, maximum fuel economy and the lowest exhaust emissions due to effective combustion. Spark plugs are available in different heat ranges and thread sizes to suit engine requirements. There are several factors - such as thread reach, thread diameter, the insulator nose projection, and whether the spark plug incorporates a gasket or is of the conical type - to consider when choosing the correct spark plug for your needs. When buying these spark plugs by NGK, you are guaranteed that they will meet or exceed OE quality and performance.

These products are adequately protected from combustion gas leaking through the shell thanks to triple-gasket sealing and built with a solid-copper core that produces a more powerful spark with less firing voltage, while most other spark plugs on the market feature only two seals and use a "copper coated" center core. The spark plugs also feature the alumina silicate insulator that is virtually pure to insure dielectric and physical strength, as well as heat transfer away from the tip for maximum performance. To eliminate “flash over,” which can cause misfiring, these products are built with corrugated ribs and feature cold-rolled threads to prevent damage to the cylinder head and make installation and removal easier. In addition, the product is zinc chromate coating double-dipped using exclusive NGK technology for maximum corrosion protection.
