Clear the damaged thread with a standard drill. To repair a spark plug thread no Pre-drilling is necessary if using the special Spark Plug Tap. Check that thread and pitch of the tap and the bolt match. Use the special V-COIL-Taps for cutting the holding thread into the cleared hole.
It is recommended to use suitable cutting oil. Please insert on installation tool and position the adjustable ring so that the insert tang is centered in the tang slot.
Wind the insert in with a light downward pressure until a half turn below the surface. Don't work against thread direction as the tang could break.
