And for the sake of all sanity and all that is holy, use only ACDelco platinums. NGK and Denso's are ok too. Same for standard plugs. Bosch platinums and GM engines don't mix <img src="/forums/images/graemlins/shame.gif" alt="" /> 1990 Montero RS (In pieces... for now) KG6VNX Re: spark plug gap [Re: 52degrees] #743087 08/09/06 04:16 PM Joined: Jan 2005 Posts: 178 Maryland 4 4mudder OP Wheeler I found the sticker it says .035.
