NINEFOX Spark Plug Thread Repair Kit M14x1.25, 11 Pc Insert and Tap Set

About this product

Description This M14x1.25 spark plug thread repair kit is made for restoring damaged spark plug threads in applications that require M14x1.25 sizing. It supports thread repair, rethreading, and insert installation in compatible cylinder heads when the selected size matches your repair needs. The 11 piece set includes 10 thread inserts and 1 tap, giving you the core components needed for size-specific spark plug thread restoration. The inserts are made of stainless steel, and the tap is made of high speed steel for repair work that depends on correct sizing and controlled use. Before buying, please confirm your spark plug thread size is M14x1.25. This kit is not a universal fit repair set and should not be used for other thread sizes. No drill is included, so please check your tool setup and working access before purchase. For best results, clean the spark plug hole first and keep the tap aligned during cutting. Back it out periodically to clear chips, then remove metal debris fully before installing the insert. Final spark plug installation should follow the required specifications for your application.
