I had to re-gap new NGK Iridium spark plugs and the usually available tool was not up to the task. This was easy to use and came with a feeler gauge that had useful increments.
Perfect gap tool, easy to use and you don't have to worry about damaging the electrode
I have my own work shop. This tool arrived in GOOD CONDITION. And I guess, it's going to be the best spark plugs gap tool that anybody could have… No matter the price…
So far this product looks like the high dollar ones on the market. The screw adjustment works fine. I put a little oil on the threads before tightening the adjuster.
