What power are you running? Here's part of an email from Mark at CS 6EIX plugs will be fine. The suggested plug by NGK for a standard car is the 5EIX, and we use the cooler 6EIX in standard and cars up to around 300bhp, so the 6EIX is already a cooler plug than the original recommendation and will be fine
