The gap is between the center and ground electrodes...slight drag on the feeler gauge.

Yeah, I know what the gap is. Where is it supposed to line up on the feeler guage? Is it supposed to stop right in the middle of the 55 mark? Thanks!

Well, I used my torque wrench on the plugs, anti-seize on the threads, and used extra boot grease on the plug wires to make the second time around a little easier

The back right one is easy. No tricks, just a 3/8 ratchet and a 5/8 deep socket.

EDIT: Well I have ASM headers so your's may vary.

Take your time installing them, and not crossthread, use a little smudge of anti-seize on the plugs, and dont overtighten.
Thanks for the advice about using the wrench with the hex socket! It's the only way that worked, since I'm kinda limited on tools and only had a 4" & 8" extension.

Your feeler gauge is of the same thickness across the blade - it doesn't matter about 'lining it up'

Glad to be of some assistance. I had the same problem, extensions were either too short or too long. How did your old plugs look? Mine came out around 60,000 still looked like new other than the coloration.

He was probably using one of those round ones with the gradgitated marks or whatever you call them around the edge and gapping hole on the side.

They were pretty dirty I have ~74,000 miles on it and the last time they were changed was ~5x,000.
