Review on Lisle 20700 Coil-on Plug Spark Tester: Enhance Spark Plugs Diagnostics with Ultimate Precision by Meech Elliott

Revainrating 3 out of 5

Great tool! You need to know the secondary resistance of the coil.

instructions rather poor. Once I figured out that I needed to know the secondary resistance of my coil, it was easy to set the resistance on the unit. no need to change the coil.

Pros
  • GOLS certificate
Cons
  • interval
