    Perfect.

    The Right Insert

    Excellent product, very well made and just the thing to repair a blown spark plug hole. You need the kit to install them but it ends up better and stronger than the factory head.

    Spark Plug Insert for Ford

    2002 Ford F150, 4.6l with 285k miles, Cylinder #3 Watched several YouTube videos. Used locktite on threads and JB Weld on lip of insert as suggested by Ron Williams. Waited 24 hours and fired it up with no issues. Took it for a 200 mile trip a few days later. Feels solid.

    Very Dependable

    I have put at least 100 if not more of this in and never had one to fail or blow out.

    More threads for spark plug

    If you watch the repair videos carefully using JB weld under "lip" of insert and proper locktite for threads. Insert provides multiple threads for spark plug unlike the original 4 threads in the factory cylinder head. Take your time. Am now a couple days for JB weld and loctite to set.
