whats the best plugs to put in a 1994 wrx at the moment ive got denso irridium tipped but ive been told the tips can break off :thumb:

I've got NGK PFR7B in my 93wrx at the mo, no complaints at all. :) Was advised to use these on a modded engine as their a cooler running plug.

I've been running NGK 7B's also, Perfect for a light to moderate state of tune
