Long Reach Spark Plug - Internal Thread Restorer Set

AST6040 is a special long reach (260mm) thread restorer set for 16v. and V6 engines with deep seated spark plug threads. 

AST internal thread restorers pass down through the spark plug hole and then expand into the good threads at the bottom of the hole. By working the restorer back up the threads, it aligns and restores minor cross threading damage as well as cleaning the threads.


Individual Thread Restorers within the Set:

    • AST6041 - Long Reach Thread Restorer 12mm

    • AST6042 - Long Reach Thread Restorer 14mm
