NGK Iridium IX Performance Spark Plugs
Details
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
