Spark Plug Thread Repair Kit M14 x 1.25 25 Piece Metal Case

A 25 piece spark plug thread repair kit for restoring damaged or stripped M14 x 1.25 spark plug threads. Supplied in a metal case, it includes the key tools and inserts needed for thread repair, including for deeper spark plug recesses where access can be awkward.

Used for vehicle maintenance, servicing and engine repair work where spark plug threads have worn, stripped or need cleaning up before refitting a plug. Suitable for garage work, workshop use and experienced DIY repairs, especially on engines with deep-seated plug configurations where extra reach helps when working down inside the plug recess.

The thread repair insert kit includes a plug tap, step tap, seat cutter, insert drive, wrench, T-bar and coil inserts, giving you the parts needed to carry out the repair in one set. The stepped tap helps with correct cutter alignment in the existing spark plug hole, while the extension tools make it easier to reach the bottom of the recess. With 10 inserts at 15mm and 10 inserts at 9.4mm included, it covers repeat jobs and different repair depths, which is useful for regular maintenance and workshop repairs. The metal case also helps keep the pieces together between jobs and makes storage more straightforward.
