Spent quite some time searching the forum and need some help!
Which plugs should I be using in my Rev 3 Tubby running 1.2bar, CC, Power FC 310BHP. Should it be grade 7 or 8? I'm going to run copper cores I think, just after a part number?
Many thanks!

.7 is prob your best bet ah kid...lol...if there is a rule of thumb it's...the more power you have the shorter the gap, if you develop a missfire/stutter then you can close the gap a tad more...mine are 0.7 and I have the usual mods, IC, filter, downpipe etc running 1 bar of boost.
