AUTOOL SPT101 Car Spark Plug Tester – Dual Hole Detector, 12V Ignition Analyzer

Got a misfire or just want to check if your spark plugs are doing their job?

This AUTOOL SPT101 tester makes it super simple.

It's a dual-hole detector, meaning you can test two plugs at once or just have a backup connection.

It works on 12V gasoline vehicles, and you can simulate engine speeds from 0 all the way up to 6000 rpm to see how the plugs perform under load.

The tester itself runs on standard 110V or 220V house power.

It's compact—about 145 x 85 x 113 mm—and weighs around 490g.

Adjustable and auto-sensing, it gives you a clear read on ignition strength.

Comes with a 3-year warranty.

Perfect for the home mechanic or pro shop.

Made in China, solid and reliable.
