๐Ÿ“‹Frequently Asked Questions:

Q: How to use this?

A:

  1. Cut a larger threaded hole in the cylinder head with a tap.
  2. Screw insert into the head.
  3. Screw plug into the insert.
  4. Use an expander to help seat insert by tapping with a hammer.
  5. Select insert that covers as many of the plug threads as possible to avoid carbon buildup (this can make unscrewing the plug from the insert difficult).
  6. Use grease on flutes and any cutting tool to catch shavings, clean often, and vacuum when finished (grease not included).

Q: What is the thread size?

A: It's 14mm.
