NGK - Features NGK - Spark Plugs Installation NGK - Spark Plugs Overview


  • Designed for faster starts and quicker acceleration
  • Better fuel economy and lower emissions
  • OE approved design
  • Laser welded iridium center electrode tip
  • Platinum disc welded to backside of ground electrode
  • Ideal for applications with DIS (Distributorless Ignition System) “waste spark” ignition systems that require double precious metal spark plugs
  • Manufactured using triple-gasket sealing process to prevent leakage through the shell
  • Alumina silicate insulator for strength and optimal heat transfer
  • Cold-rolled threads for easier removal and installation
  • Corrugated ribs eliminate misfire causing “flashover”
  • Trivalent metal plating
  • Last 80 to 100 thousand miles

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. They feature a laser welded iridium center electrode tip and platinum disc welded to the backside of the ground electrode to provide superior ignitability and a slow wear rate for an exceptionally long service life. These plugs will provide quicker acceleration, stable idle, improved fuel efficiency and lower emissions while lasting 80,000 to 100,000 miles.

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.
