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
