Spark plug hole repair kit for Porsche 911



Stripped spark plug threads in a 911 head usually means one of two things– a compromised repair or an engine drop to do it properly.

Until now.

STOMSKI RACING's new 911 Spark Plug Hole Repair Kit allows you to either accurately chase the threads of the damaged head, or if necessary, effectuate a complete fix by installing a Time-Sert (or Big-Sert). Our new digitally designed and CNC machined jig mounts over two of the valve cover studs, and when locked down with the included thumb screws, allows Time-Sert reamers, chasers, taps, and setters to be precisely aligned by way of the jig's guide tube and custom tap driver– all while the engine is still in the car.

Available in two different versions:

• SR130 for use with the standard M14x1.25 TimeSert Kit, and Inserts (TS4412E & TS44111) and;

• SR130BS for use with Big-Sert M14x1.25 oversized Insert Kit, and Inserts (TS5141E & TS51407).


We also have Time-Sert/Big-Sert 14x1.25 Kits and Inserts available for the complete package.
