Also, both NGK and Bosch are HEX(6 sided) plugs. Why do you need a 12 point 5/8 socket?


sorry bud you should have sent me PM as I don't frequent this site that often. If it is not too late, I did not check the gap You know me, I am not too mechanically savy but thanks for pointing that out for other members.

I got the plugs from Tischer and thought it was gap for my car? I think a 12 point socket has thinner wall so you can fit into the chamber. But so far, car run great ever since I had changed the plug.
under construction!
