Hi, can anyone tell me which model of ngk spark plugs are best suited on my 2001 bugeye wrx. It is modded to 270bhp at the moment soon to be in the 300's with new turbo etc

I fitted ngk 7's about 18 months ago but have a slight hesitation on acceleration so may fit new plugs with my cambelt change to see if it helps.

Any advice would be great

Cheers

I would have suggested that the NGK PFR7B would be ideally suited to your car.

Cheers Rob I'm pretty sure that's what I have fitted but hear people talking about 8's and 9's ??

wouldnt have thought the 8's or 9's would be needed at your planned level of tune to be fair

They will be fine mate, My above post when I read it back probably wasnt clear lol. I suggested the 8's and 9's wont be needed for the op's planned power. The 7's will be fine up to and above 400

Make sure they are gapped properly.

Also boost it now and again, as I have been told if you don't boost it they need a clean.

I went through a set of sparks as misses was driving like miss daisy.
