🔍 Accurately Measure Spark Plug Gaps with GEARWRENCH 166D Small 6 Wire SAE/Metric Gap Gauge Review

I don't understand why they aren't that easy to find, they are so much better than solid gap tools. With this tool you can close the gap if you make a mistake and make it too big. Worth every penny!

Looks solid enough. I had a car but it didn't have the smaller gaps used for lawn mowers. This covers all the bases and is well suited for use in cars and small engines. This is safe for the expensive iridium plugs that come in cars.

Works great except lacks all the big gaps modern plugs require. I just made a 2002 Malibu with a .060 spec, the largest tool gauge is .045. Most electronic ignition vehicles have large gaps. Still worth doing for small motors and notches for bending the electrodes.

great tool. This was the first time I've had to change spark plugs and had to replace 16 of them because I have a Hemi with an aftermarket supercharger. This tool made it very easy and safe, I didn't damage any. Plug. I'd also recommend getting a good distance meter to make sure you're on the right track!
