Review on πŸ” Accurately Measure Spark Plug Gaps with GEARWRENCH 166D Small 6 Wire SAE/Metric Gap Gauge by Michael Zambrano

Revainrating 3 out of 5

Better for small engines, gauges are too small for most 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.

Pros
  • Easy to read control panel
Cons
  • Useless features
