Universal Spark Plug Gap Tool with 32 Blades Steel Feeler Gauge for Most 10mm 12mm 14mm 16mm Spark Plugs Red

Have used several times still sharp and cutting thru filters perfectly. Easy to use. Fits every filter I have needed it to. Has not giving me one issue works perfectly

Nothing wrong with the quality or design but the feeler gauge only gauges up to .035 which most cars now are from .040 up to .055 but the .035 gauge had a thinner gauge next to it which made it come out to .040. You just have to add enough thinner gauges to get higher than the .035.

Good quality. On time delivery.

its different to use compared to the little disc item i have always used, not hard to use

Nice product, good shipping

Red Finish is nice. Tool works well. I had a few spark plugs to set the other day. Having a good size wheel with good thickness is a big plus. If wheel was smaller or thinner, it would be more difficult or more uncomfortable on your fingers to bend the spark plug ground terminal. The screw is easy to turn, but you need to have screw press tightly to get ground electrode to bend and not spring back as much. I needed a gap of 0.035. I found that I needed a feeler gauge of 0.032 or even 0.030 to bend electrode and have it spring back to 0.035. Using a feeler gauge of 0.035 to bend electrode to 0.035 isn't going to work. You have to downsize the feeling gauge that you select to fill the gap when turning the wheel. But once you select the right one, you are set. I was working with NGK Power V 7252 copper core with nickel terminals. I use an accurate gapper tool to verify that spark plug gap did get set to 0.035. Make sure to verify using your feeler gauge or some other gap measurement tool.
