For those who are meticulous and want the maximum precision in the spark plug gap, this simple accessory precisely calibrates the ignition gap of the spark plug. Simple and intuitive, just slide the spark plug into the guide and stop at the recommended measurement on the maintenance manual... On my Mercury 115 CT engine, the gap was 1mm. The measurement in inches is also indicated on the opposite side... Recommended, great price!

The product quality is very good. It seems to be made of steel. This is a very good product to buy. It can be used as a keychain.

It arrived super fast in a week, I had one like this before but I lost it and it's very useful.
