Hi,

I have got to change the water pump on my classic, while doing so, spark plugs and cam belt are being done.

What ones (spark plugs) are better to use please

Its a wrx, but with an Sti engine, pro va ecu, making an estimated 320bhp

Thanks for any help you can offer

 

I'm using NGK PFR7B's in mine, its a V4 sti - reckon these will be fine for yours too. Make sure they are properly gapped though, recommended gap is 0.7mm or 0.65mm, mine are running 0.7mm at the moment.

Hope that helps

Cheers

Pete
