Hi
im in the process of servicing my 1996 sti v2 , the car is running on 22psi boost and judging from the previous owners bills it has eaten plugs , he has only been using NGK standard plugs for this model, im thinking of using a harder HKS plug, any opinions on this please and they look a pig to change "are they????????????" thanks for ny help

Easy to change with the correct socket, knukle and extention.
Remove the screen washer bottle.
NGK PFR 7B. Avoid Iridium plugs or plugs with a big price tag.
22psi is not that much.
Reduce the gap to .6mm if you are worried about the boost but it will probably be OK at .7 mm.

Iridium : They break. Send e-mail address for photos of several.
Expensive : Until you are at high boost they are not required.
