Universal Spark Plug Gap Tool for Most 10mm 12mm 14mm 16mm Spark Plugs Black

This is the absolute best spark plug re-gap tool. I bought another style that didn’t work because the plug didn’t fully thread into the body. This made it sooo easy to gap precisely. I love love love this tool.

Talk about a perfect gap every time. I ran a test to see what the spring back of the plugs would be. I needed to gap them to .016 so used a .012 feeler gauge and every plug game out perfect to .016 No more tap and guess and hope you didn’t go to far. This thing is awesome. It’s built beautifully, strong and durable. I expected a cheap plastic twist knob but it’s actually a very nice, knurled aluminum knob. Just lock it in a vice and you have complete control. I just did 8 plugs in just minutes compared to the old tap and pray. This will definitely be in the tool box at the track.

I like this tool for sure help me regal plugs with ease, really well made should last many many years not the most expensive not the cheapest but really good other the price

Item works like it should. Probably be alot easier to do away with the knob and install a T-handle to make it easier to close the gap.

I’m really impressed with this. It’s overbuilt, over engineered and I’ll never need to buy another. It’s built like a tank. In terms of gapping a plug, it does the job efficiently and easily. I’d suggest following the instructions and going down another thickness as the plug does tend to spring back slightly; this is to be expected. Great tool if you’re working on engines!

It works well and built well but I still think it is way overpriced. especially the few times I will ever use this in my life.

I guess you get what you pay for. This tool is near unusable. I had to remove the knob and attach vice grips to the all thread rod it has on it because every half turn the unit would bind up.. waste of money, don’t buy it.

Good build quality , much better than using the coin and tapping the head of the spark plugs. This let's you get the job done faster, more consistent, more accurate, and it's harder to make a mistake.
