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 power, 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.

Designed to provide maximum performance and extremely long service life, these spark plugs are a great option for modified engines and appropriate replacement for OE nickel alloy and single precious metal spark plugs, where recommended. They feature a 0.6mm laser welded iridium center electrode tip that is extremely resistant to heat, corrosion, and electrical wear. The reduced mass of the fine wire center electrode tip and taper cut ground electrode provide more area for flame expansion, resulting in quicker starts, improved performance, and better efficiency.

The products are adequately protected from combustion gas leaking through the shell thanks to triple-gasket sealing, while most other spark plugs on the market feature only two seals. 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. The products also feature trivalent metal plating for superior anti-corrosion and anti-seizing properties.
