With indexing the AR3933 spark plugs. If the crush washer does not give it the right position and you install the moroso washer (1 of 3) are you supposed to reinstall the crush washer or leave it off the spark plug since you have a indexing washer on it?

I've always lrft the washer on the plug, makes sense to seal against the indexing washer. Joe

Randy, wide spark plug gaps went out with ignition points. With todays MSD's and most other manufacters electronics, there is no reason to run more than .025 gap. As a matter of fact, if your trying to run, say .040 - .050, close the gap down to .020 - .025, and you'll see a performance gain. At least that been my experience.

on AR3933 plugs leave the gap alone --run em as they come from the factory just check to make sure that the gap did not close up ratteling around in the boxes---Comp 387

I don't know about the cyro , but I do sell alot of Autolite AR 3910X and AR3933X to the go cart guys. It's a surface gap plug that has proven to be worth some big gains on their dyno.
