Review on 12mm Spark Plug Caliper: Universal Gap Tool for Precise Spark Plug Gapping - Black by Fred Novak

Revainrating 5 out of 5

Does the job: Replacement parts

Wanted to change the spark plugs on my 2015 Kia Forte5 (Hatchback). I've never made plugins before, but there are enough videos on YouTube to find out. The job was easy and this tool helped me safely insert new connectors without damaging them.

Pros
  • INSTRUCTIONS: Simply insert the spark plug into one end and turn the knob on the other to push gently, evenly and slightly to close the gap until the right gauge is found.
Cons
  • Some issues
