spark plugs

[Tommo]

I've been having a bit of a missfire when the cars under boost, so tonight i finally checked the plugs. the tip og the plug is like a point, i thought they were more square is this right? one plug was black up the thread and not in to tight, was this my misfire culprit? will run car tomorrow when i have time
The plugs are NGK PRS7A, should i need to uprate trhem as i've upped the boost with the avcr? wot do you all reccomend/use?
Cheers guys

Tom hun they are not the right plugs

You should be running NGK 8EIX or HKS S45G's

Would that explain why i get a missfire under boost?

also the loose plug will have given you some funny running/noises.....................

personally would use the DENSO IW22 in most std'ish cars..........cheaper than most due to the fact that DENSO actually make them for a lot of "branded" tuning companies.................
