Superfire Spark Plugs
HKS SuperFire spark plugs now use the new 'Iridium' centre electrode for even better performance and longevity than the older Platinum types. Although the SuperFire plugs are a high performance plug, they will still allow for easy start-ups and prevent mis-fires during warm up.
The insulator is a perfect blend of materials, volumes and measurements designed to maximise the elimination of detonation.
We advise the fitment of these plugs for any Japanese vehicle that has been modified over standard, and especially for turbo vehicles running higher than stock boost pressures.
Three different heat ranges are available, equivalent to NGK heat ranges 7,8 and 9 to provde a plug for every engine type.
Price £14.50 each.
