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 ensures versatile compatibility across all ignition systems. Built for durability with a replaceable bulb and backed by a limited lifetime warranty, this tester is a must-have for precise, long-term engine troubleshooting. ## 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: This is a solid, functional tool designed for long term use that outshines cheaper versions - Bottom line up front, if you're considering buying an inline spark (plug) tester, I highly recommend buying the Lisle version. Sure, you'll spend a bit more on it. For me, it was a "one time use" purchase however this was my *second* purchase because I bought another much cheaper brand the was broken upon arrival. In short, I didn't save any money buying the more affordable version. This Lisle tool is as all others have said, a very solid product with a bulb you can actual find and replace. It is well made, durable and will last for many years of use I'm sure. 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.... ## Features - 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. - Quickly diagnose problems with all ignition systems ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09NMHFGXD | | Best Sellers Rank | #2,965 in Automotive ( See Top 100 in Automotive ) #10 in Spark Plug & Ignition Tools | | Brand Name | Lisle | | Color | for all Ignition Systems | | Customer Reviews | 4.7 4.7 out of 5 stars (6,788) | | Global Trade Identification Number | 00083045205807 | | Included Components | tster and wires | | Item Dimensions | 7 x 14 x 2 inches | | Item Type Name | Tester | | Manufacturer | Lisle | | Model | 20580 | | Power Source | Hand Powered | | Style Name | InLine Spark Tester w/ Coil On Plug Wire | | UPC | 083045205807 | | Unit Count | 1.0 Count | | Warranty Description | Limited Lifetime | ## Product Details - **Brand:** Lisle - **Color:** for all Ignition Systems - **Item dimensions L x W x H:** 7 x 14 x 2 inches - **Power Source:** Hand Powered - **Style:** InLine Spark Tester w/ Coil On Plug Wire ## Images ![20580 InLine Spark Tester w/Coil On Plug Wire, One Size, Factory - Image 1](https://m.media-amazon.com/images/I/61EZ+kYrEcL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ This is a solid, functional tool designed for long term use that outshines cheaper versions *by A***. on March 28, 2026* Bottom line up front, if you're considering buying an inline spark (plug) tester, I highly recommend buying the Lisle version.
