The Lisle 20580 InLine Spark Tester is a polished, hand-powered diagnostic tool designed to instantly display ignition spark via a bright flashing indicator. Featuring a dual-ended wire with both straight and 90-degree boots plus a 7-inch extension for hard-to-reach coil-on-plug wires, it offers universal compatibility across all ignition systems.

## Description

Connect the tool between the spark plug and the plug wire. The short wire is double ended to offer a straight boot and a 90-degree boot on one tool. With the engine running, the tool flashes a mirror image of the ignition spark. The additional 7" extension plug wire is used on coil on plugs that are recessed and hard to reach.

Review: Why did I wait so long to buy one of these? - This device saves so much time trying to determine if a small engine has spark. It is so much easier than pulling the spark plug and trying to prop it up against the case of the engine to see if it has spark. Just hook this up inline to the spark plug, crank the engine, and get immediate feedback that spark is present. This is great.
Review: Great item - Good quality, easy to work with, works great, bright light, like the longer boot for coil packs. Struggled with the shorter one in the beginning. I have the dreaded 5.4l 3 valve v8 F-150 and sparkplugs were just to start with....
