I just bought a set of G-Power Platinum plugs for my 351 Windsor.
Look like great plugs .
Has any one out there used these before ?
They are gapped at 35 that is what is called for in 1985 ford f250 truck with a 351 windsor.
The Engine is in my 1982 mustang.
I have been looking for the proper plugs for my heads and they are World Products (Windsor) Cast heads.
The only info for plugs that I got from Summit was that those heads take a 14 mm with 3/4 reach.
Hmm not much to go on.
Any help would be great thanks....Ray.
