Gets the job done. Successfully gapped my bosch spark plugs.

Great product!

It's a spark plug coin tool. Inexpensive and works perfectly.

picked up a spark plug gap tool for my 2016 Honda Civic, and I’ve got to say, it really made the whole spark plug change process a breeze! Before using this tool, I was a bit intimidated by the idea of gapping spark plugs, but this gadget made it super easy. It’s straightforward to use, and I love how it gives you precise measurements. Just a quick adjustment here and there, and I was good to go!

It's easy to check the gap, and narrowing the gap is easy enough just pushing on the plug tip, I agree with other reviews that it's hard to use the tapered hole that is intended to be used to widen the gap. It's not a showstopper, the most important thing was being able to measure the gap and if I need to use a small screw driver to widen it, that ok.
