Default Confused with which spark plugs

Hi All,

I've got a 2002 Bug WRX running approx 340-350bhp, can someone please point me in the direction of the correct spark plugs, done loads of searching on here but struggling to find the answer.

Aye, mine is running about the same, and I agree with the above, unless your mapper says different.

Andy Forrest's website is good for this kind of info - just google it.
Plug gap is 0.7mm BTW.

No need to gap them down if your on newage coil packs.

As I said - unless your mapper says otherwise, also you do need to gap down if the boost you are running dictates...
My gap advice comes from Andy Forrest - so if you want to debate the point with possibly the best mapper around.... I would like to sit in.
