Excellent Spark Plug Tester – Easy to Use and Accurate
This spark plug tester works exactly as expected. It is very easy to set up and use, and it quickly helps identify whether a spark plug or ignition system is working properly. The adjustable RPM feature is useful for testing under different conditions, and the display is clear and easy to read. The build quality feels solid, and it has already saved me time diagnosing engine problems. Great value for the price. I highly recommend it for DIY mechanics and professionals alike.

Excellent Tool
The AUTOOL Car Spark Plug Tester is an absolute game-changer for diagnosing ignition issues. I used it to test several plugs from different vehicles, and it worked flawlessly every time. The dual-hole feature is super convenient—it lets you compare two plugs side by side, which really speeds up the process. It’s simple to operate, well-built, and surprisingly powerful. The adjustable frequency is a nice touch, allowing you to simulate different engine speeds and get a clear look at spark strength and consistency. Whether you're a professional mechanic or a DIY enthusiast, this tool is worth every penny. It’s saved me time, money, and frustration.

Doesn't work for Small equipment spark plugs, but description DOES say CAR
I bought this tester but mostly test small engine plugs, so I needed to modify it (Not much difficulty) to handle small engine spark plugs. Now I have a tester that does both.

Handy tool
This thing is great had a motorcycle that would randomly drop a cylinder coil tested good injectors tested good pulled the plugs from the rear cylinder and one of them would just stop working when it got warm . Great for a visual on something you would never see .
