I can't seem to be able to fit my socket in the spark plug hole of the far inner passenger side spark plug. Ihave k-code headers and they seem to be a tight fit. Any tricks of accessing this spark plug without removing the header? 68 mustang with a 289.
By "K code headers", do you mean iron exhaust manifolds? There are a few ways to go about this. Install the spark plug by hand, that put the socket on for that last 1/8 turn. Get a socket with thinner walls. Stuff a rag in the spark plug hole and use a die grinder to knock off the corner that's causing the problem. It won't take much.
Yes I bought the k code headers. I was able to remove all of the plugs except the corner passengers. I will try the 13/16 thin wall socket if I can find one. Thank bro!
