Lisle inline spark testers offer a visual check of your ignition system. These Lisle tools flash a mirror image of your ignition spark so you can see exactly what's happening. Simply connect these spark testers between the spark plug and the plug wires and start your engine. The tools are double-ended to fit straight and 90 degree boots, plus any ignition system can be quickly diagnosed for problems. It's time to tune up with Lisle inline spark testers.
