Review: Works great - Love old school tools
Review: Adjust-ability is Great - Works as advertised and the gap adjust-ability is great. I used it to test the gap ranges on used and new ignition coils to get a feel for the maximum gap the coil would cross on each plug wire. Very insightful. Would buy again and recommend.

To use, attach the alligator clip to the engine, connect the other end to the spark plug wire and check the spark length through the small window. The longer the spark gap, the stronger the coil

### ⭐⭐⭐⭐⭐ Works great

### ⭐⭐⭐⭐⭐ Adjust-ability is Great

### ⭐⭐⭐⭐ great design but....
*by D***R on September 6, 2025*

I liked the option of adjusting the gap to check the strength of the spark, and the alligator clamp to get a good ground. The price was right, and the quality was good. My only complaint is that the head that goes into the ignition wire doesn't fit securely. It is removable, and it would have been nice if there were different heads to fit different applications. I will remove some from old spark plugs I have around the shop and see if they will screw onto the tester.
