So I'm changing out the plugs in my car. Bought some copper motorcraft plugs. Just curious if there's a different spark plug gap other than stock that people recommend or like to run. I've read that a lot of people run it a little tighter than the .054" stock spec. They weren't running any power adders, and neither am I. Let me know what you think.
This is a surprisingly difficult question to find an answer for on the intrawebs. Lots of threads about the stock plug gap, but nothing on what you should really gap them at.
I feel like .054 is pretty wide too, but didn't want to be all nilly willy and gap them at .045 without asking. I'm no pro. Anybody else have any input?
