Fairly nifty concept. As soon as the threads are began, then use a ratchet extension and provides the plug a few quarter flip beneath rigidity however no extra as you can break the porcelain when you over tighten.
A bit of dab’ll do ya
Earlier than changing the coil, add a dab of dielectric grease to the tip previous to putting in it over the spark plug terminal. Plug it again in to the ignition wires.
