The most inaccurate gapping tool
I don't normally write reviews and if I do, it's either because a product impressed me so much, or is a piece of trash and I need to warn people about it. This case is the latter unfortunately. I gapped my plugs using this tool to 0.024". Just for safety, I compared the gaps using my trusted mechanic's tool which I know is spot on. My 0.024" reading was 0.026" on his tool. That's a variance of close to 10% and that makes a huge difference in highly tuned applications and could cost you an engine. Bottom line, don't buy. Even with thousands of positive 5 star reviews, more often than not the 1 star reviews have true value and in this case please read them.
