Coin-style spark plug gap tools are CRAP!! Feeler gauges are bestest!!

Kinja'd!!!

I never knew how easy and accurate these were to use until last night while fiddling with some spare plugs. Everyone must have one of these!!

That’s all.

Haha, yes! Those things suck. Know what’s even better for spark plugs than flat feeler gauges, though? The wire-type ones.

the nice thing about the coin ones, is that there is no fiddling with any other sizes or moving parts. you just start the plug in a shallow size, and wedge it around to where you need it to be at, gap wise. but nothing replaces a good set of feelers when running valves.......

Sniff. It just crackles this old, crystalline heart to see you young bucks larnin’. Coin gappers suck. Get a real stainless or hardened set of feeler gauges and keep ‘em close. A tenth or 2 off and yer mileage will vary. Can’t get that close with coins.

Used to carry a cut down 35 on my keychain for the plugs in my ‘56 Chevy cause we changed the plugs and points so often. And it looked cool.

...but you can’t stack the wire gauges on each other to get a different size, like you can with flat ones.

Good point.

I did take some searching before I finally found a tool with the 0.54 feeler that my car’s spark plugs call for.
