🔧 GEARWRENCH 3293D: SAE/Metric Spark Plug Gap Gauge - Accurate Tool for Precise Measurements Review

Of all the spark plug tools I've used, this is my favorite design. Easy to read, easy to use, easy to set distance. A decent size and a good weight. I highly recommend it.

I always have spark plug gauges with me. A standard gauge in multiple sizes both inch and metric and then I have this one that allows you to more accurately measure what your exact current distance is.

This is a really easy way for beginners to quickly determine the gaps in their connectors. I consider myself a beginner and appreciate it compared to the old fashioned "wire" type my dad had. On the other hand, I found it difficult to use the gap adjustment tool. I missed a lot and had to use another tool to fix the error. I've just never been good at tightening tolerances - loosening was fine though.
