I've searched for this on here with no luck. I'm looking for some plugs for my sti with 330bhp. I've read somewhere that ngk iridium heat 7 would be good. When I ask in part shops they are struggling to tell me which ones are right for my engine as my car reg comes up as a wrx. It was originally. So the ones I've found are part no. 2667. Description is bkr 7. Does this sound right? Any help would be appreciated. Cheers

Hi there

NGK PFR7B are preferred on STI or on WRX,as they're proven and tested on numerous cars,we run PFR7B on the wagon which has run 490bhp plus NOS without the single issue

We run too BKR range on the wagon too,but not 7's range,but BKR8EIX when we are run 555.5bhp

But what I've read Iridium spark plugs are bit fragile and doesn't last as Platinum

Thanks,Jura
