A tool to assist in gapping spark plugs. Simply load the spark plug in and apply pressure using the dial until the proper gap is verified with a feeler tool. I have a list of known working spark plugs below, but any similar 16mm spark plug should fit. If you verify it works for another and you put it in the comments I will add it to the list.
Be sure to glue the dial together once the bolt is loaded in. Same for the bolt to the gapper tool. You can try a press fit, but I am not sure how long it will last before slipping free.
Parts Required:
1 M6x35 (or larger) bolt
1 M6 nut
