Toledo Spark Plug Thread Chaser

The Toledo Spark Plug Thread Chaser is an essential restoration tool designed to breathe new life into damaged or fouled spark plug threads. Featuring a tapered, double-ended design, this versatile instrument caters to both 14mm and 18mm spark plug threads (M14 x 1.25 & M18 x 1.5), making it a valuable addition to any automotive toolkit. It provides a simple yet effective method for maintenance, allowing users to run the tool through existing threads to clear away stubborn carbon build-up, corrosion, and dirt that can compromise engine performance.

Beyond simple cleaning, this thread chaser actively straightens and deburrs threads, ensuring a smooth and secure fit for new spark plugs. Its 75mm overall length makes it accessible and easy to handle, while the hex design allows for operation with a deep socket, open-end spanner, or box wrench. Whether you are prepping an engine for a tune-up or addressing specific thread issues, this tool delivers a professional finish. Please note, to ensure the integrity of the engine block, it is recommended that this tool be used by those with mechanical experience to avoid accidental damage during the repair process.
