|A complete spark plug gapping solution for field or bench use includes the Heavy Duty Spark Plug Gapping Tool to accurately set your spark plug gaps to within 0.001". You also get a set of wire feeler gauges to verify gap size. If you should happen to accidentally over-gap the plug, then the included Gap Expansion Tool will get you back on track. And finally, included in the Kit is an Electrode Erosion Gauge to make sure that your gapped plugs are still in serviceable condition.|
This is a nice kit. It is a little expensive for what you get, but everything is very nicely made and quite heavily constructed - heavier than I expected it to be.
Not used yet but first impressions are very positive. Looks well built and was well packaged.
It works. However, the wire gauge is made from cheap plastic. The rest of the kit is quality made.
Yes, this would work with all Tempest and Champion aviation spark plugs.
Works with 18MM spark plugs only.
