I don’t know what to say other than the fact that it works well and then I’m happy with the product. It’s very well made of heavy duty materials and I’m looking forward to using it for a long time.

It gets the job done but it bends quite easily

It’s a gap tool. What can I say? It checks the gaps really well I guess. 😂

Ordered this to slightly increase the gap on my spark plugs. I was only able to adjust two of them since the tool is too soft. and it got quickly deformed.

I put the CTA Tools 3238 9 Wire Spark Plug Gap Gauge to the test, and I’m impressed with its performance. Although it’s a very basic tool, it does exactly what it promises. I compared its measurements with those taken using a vernier caliper, and the results were spot-on—real and precise. It’s incredibly affordable and practical, built solidly to work flawlessly on all the spark plugs I own.Pros:• Accurate measurements confirmed by vernier caliper tests• Very affordable and great value for the price• Sturdy construction• Works reliably on all spark plugsCons:• noneOverall, if you need a straightforward, dependable spark plug gap gauge without any bells and whistles, this tool is a solid choice.

Los ajustadores negros se doblan al ajustar el nodo de la bujÃa! Por el precio esperaba una mejor calidad!

Looks to be a good quality item. Metric markings one side, imperial on the other. Check your spark plug gaps without risking damage to the tip.
