Spark Plug Thread Restorer Set 12mm 14mm Internal Repair

A spark plug thread restorer set for cleaning up and repairing damaged internal spark plug threads in the cylinder head. Supplied as a 2-piece set, it covers 12mm and 14mm spark plug sizes and gives extra reach for awkward or deep plug positions.

Used for vehicle maintenance, engine servicing and repair work where spark plug threads have become fouled, dirty or lightly damaged. Handy for garages, workshops and home mechanics working on engines with deep seated spark plugs, where access can be difficult with shorter tools. It can help tidy threads before refitting plugs and is useful when carrying out routine servicing or troubleshooting misfire-related plug removal and refitting jobs.

The 270mm length is the main practical advantage here, giving better access down plug wells without having to struggle with short thread tools in confined areas. With both 12mm and 14mm internal thread restorers included, it covers two common spark plug thread sizes in one set, which helps avoid hunting around for the right tool when service work is already underway. A straightforward option for repeated workshop or garage use where thread condition needs checking and cleaning before plugs go back in.
