Its time to change the plugs on my 02 wrx sti uk prodrive, iv done a few small mods, k&n panel filter, removed 2nd cat & res box.

Should i go for either the ngk pfr6b or pfr7b. or my local car spares say i can use bosch platinum.

Also what gap should i set the plugs.

thanks

pfr7b are the best, prob a slight bit excessive at that level of tune but price difference not much and worth the extra few £ to be ont he good side of ultra safe
