Spark Plug Gap Tool - 0.1-0.02 - With Electrode Adjuster

If you don't already have one of these handy little spark plug gap tools grab a couple for your toolbox - gear bag - and one for a friend. They're inexpensive and can solve a host of engine issues like loss of power / misfires / plug fouling / premature plug wear / poor gas mileage. Who knows if the gap was correct from the factory or if it got knocked around in transit (or on the bench... we won't judge)? Peace of mind for a few bucks is an easy win with any plug or wire service. These tools are good for just about any application with a range of 0.10 inch through 0.020 inch and even include a tapered hole to adjust the electrode.
