Spark Plug Thread Repair Kit

Spark Plug Thread Repair Kits for Stripped Threads

Repairing damaged spark plug threads doesn’t always require replacing the entire cylinder head. Our selection includes kits with the tools and inserts needed to rebuild the spark plug hole and create a secure fit during engine service. Before installing inserts, spark plug thread chasers are often used to clean and prepare threads for proper repair.

These repair kits are commonly used during ignition service on high-mileage engines and aluminum cylinder heads. After restoring threads, spark plug sockets help install plugs securely during reassembly. For checking electrode spacing during tune-ups, a spark plug gap gauge tool helps ensure accurate ignition performance.
