Good To Know
Q: Will this kit repair a spark plug hole that is completely stripped? A: Yes, the reamer and tap create a new thread path for the insert, which then provides fresh threads for the spark plug to screw into securely.
Q: Can I use this kit on any engine with a 14mm spark plug? A: This kit is designed for 14mm spark plug threads, but always verify the specific thread pitch required by your engine before use.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
