Packaged perfectly. It came relatively quickly. Works. Standard candles with 21mm nut are included. When whistles work, the current is small, the spark is thin, you need to look after the magnifying glass. For visual inspection, the sparking is suitable. The tester manufacturer should increase the power at least 1.5-2 times…

I really like the way you can test two spark plugs side by side and compare the spark intensity!
I¡¯m thankful that they make such a valuable troubleshooting tool for such a reasonable price.

This Spark Plug Tester is a Good Value for less than $25. I like that it is easy to use and has a protective cover over the test plugs. This will keep dust out and help it last longer.

AUTOOL SPT101 Spark Plug Tester Spark Plug Checker
Elijah Birrell –
Thus device is perfect to test spark plugs…of all sizes. Even though some short units do not clip in, the unit will still generate a spark. Helps to eliminate potential problem sources with anything using a spark plug. If plug is good, off to next diagnoses. Saves time and money so one doesn’t guess. Very affordable, well built and should last a long time. Cool watching the spark as well!! Must have for any do it yourself or shop.

Easy way to test your plugs without some goofy setup at the engine. Easy before and after analysis of cleaning/gapping jobs.
Helen Tout –
Great diagnostic tool. If you need to test small engine plugs take a spare spark plug terminal and cut the part that wraps around the wire off. This gives you the extra length needed for the plug to make contact. Just wear gloves to remove the terminal. It gets sharp!

Easy to use, just plug and play. Love the dual-hole design¡ªit saves me time. The RPM adjustment is super handy, and the spark light makes it clear to see. Solid tool with a nice 3-year warranty.

The AUTOOL SPT101 spark plug tester is fantastic! I love its dual-hole design¡ªit allows you to test two spark plugs simultaneously. The adjustable speed range from 0-6000 RPM is very convenient, allowing you to simulate different engine operating conditions. It’s truly plug-and-play, easy to use, and incredibly reliable.
