depends on how much boost you run....but all the suggestions so far are good. I'd stay right in the middle...the units are actually in hundredths of an inch, not tenths, so it would be 0.020 - 0.024.....unless u guys are gapping ur plugs to a quarter inch lol

i would just go to your local car parts retailer. I go to O'Reilly Auto Parts. They have your regular gap guages, and some people like to try and use feeler guages.

Feeler guages are nice and flat, don't use one of the round increasing ones " looks like a fifty cent piece" its hard to be consistent with it.

The round ones work just fine, just don't get the parts counter cheapies at O'Reilley, they have better quality ones in the aisle.
