EVO IV-VIII NGK Iridium Sparkplugs (ea)

NGK iridium sparkplugs are the standard for which all others are measured. They are used by top race teams in all types of motor and auto sports and it has been a standard in our street cars and race cars for the past 16-years. We have personally used well over 10,000 sparkplugs over time in racing and to date we have had a 100% success rate.
We recommend the BPR7EIX for most stock applications and the BPR8EIX and BPR9EIX for high horsepower applications. Also if you are using a coil-on-plug ignition system, use the BKR series of plugs as the porcelain is smaller in diameter and has a better fit (and it will require the use of a 5/8" wrench)
