The spark plug serious enthusiasts rely on.
NGK's Iridium IX spark plug is an excellent upgrade for heavily tracked and forced induction engines needing a durable plug with a tip that maintains a proper operating temperature. The temperature range of these plugs is suggested for modified BMW engines with increased compression, aggressive ignition and cam timing, and/or forced induction. Getting the correct temperature range plug will maintain a temperature high enough to prevent fouling yet be cool enough to prevent pre-ignition. While there are many things that can cause pre-ignition, selecting a spark plug in the proper heat range will ensure that the spark plug itself is not a hot spot source in the combustion chamber.
Designed specifically for the performance enthusiast. Iridium IX® offers extreme ignitability, improved throttle response and superior anti-fouling.
- Fine Iridium tip ensures high durability and a consistently stable spark
- Iridium alloy has extremely high melting point, perfect for today’s high-tech, high-performance engines
- Trivalent Metal Plating - superior anti-corrosion and anti-seizing properties
- Improved acceleration, increased fuel efficiency and durability
Priced per plug. It's always recommended to replace all plugs at the same time.
