🔌 Lisle 67800 Spark Plug Gap Adjuster for Optimized Engine Performance Review

I have no idea if other reviews are accurate as far as measurements go, but for my use case I just need consistency. I'm tired of using the paper sheet flattening technique as the paper shrinks and isn't as even. Using a 0.05mm gauge provided a near perfect match to the base instantly and without much fuss. Just twist until the sensor slides freely. -1 star for tool oil, which you absolutely must remove because if it gets on your bed, it's very bad. I would prefer something that doesn't require

Like many other reviewers, I noticed a lack of precision in the resulting tool. In some cases it differs by as much as 0.005 inch and for a spark plug that is a lot. Not to mention the technical aspect, an improperly spaced spark plug can cause problems ranging from poor gas mileage to coil pack damage.

This gap has a big empty square in the middle, so it's almost certainly an empty space that all other brands stamp and resell multiple times. Price. That's the real deal. It's not as accurate as digital calipers, but it doesn't have…

I lost my favorite gap. I'm sure it will show up, but I ordered this one because I now have to unplug some plugs. This breaker has wires for 40, 50, 60 and 80 thousandths. Those are very big jumps, especially from 60 to 80. It has two more wires: .044 and .045". It's absurd to have them so tight. Was that gap useful? My car needs gaps between .040 and .044, so I might get lucky. There were two other problems. When I increased the gap, there was no wire smaller than .040 to show me as I got…
