Description
Product Overview
The FLYPIG Spark Plug Thread Repair Kit is engineered for precision and durability. Constructed from high‑grade carbon steel, the tap and inserts resist wear and corrosion, delivering consistent performance even under high‑temperature engine conditions. The kit features a tapered M14×1.25 tap that smoothly re‑threads damaged holes, and four inserts sized to restore the original 14mm thread diameter with pitches of 1.25 mm. Compact dimensions (3.19 x 1.89 x 0.94 in) and a lightweight design (5 oz) make storage and handling effortless.
Usage
Designed for both professional garages and home workshops, this kit excels in routine maintenance, engine rebuilds, and emergency repairs. Ideal for gasoline and diesel engines that use standard 14mm spark plugs, the tool works on aluminum heads and steel blocks where the plug hole remains straight. Simply insert the tap, turn with a wrench to cut fresh threads, then screw in the appropriate insert to restore full thread depth.
