POP! Goes the spark plug!

You don't want to use a Helicoil in this application, you want to use the insert. It replaces the threaded section with a new threaded section that has far more threads (12 IIRC) for the plug to thread into.

The Lock-N-Stitch kit has a lock pin that gets installed after the insert so the insert itself can never back out.

You use the original type of plug in these inserts, and they situate the plug in the exact same location they were originally. There is just a lot more holding them in now.

When using anti-seize on anything where it's not specifically called for, you generally reduce the torque for that fastener. 10% is usually a good rule of thumb.


This is correct, which is why I torque to 10.5 ft-lbs with anti-seize.
