Damaged spark plug threads in the cylinder head can occur in any type of vehicle. Ford seems to have the most problems, however with all the cars today using aluminum heads; it’s becoming much more common problem. We get questions all the time on application for a wide range of car makes. Manufacturers like Toyota, Lexus, Honda, Acura, BMW Mercedes-Benz, VW, Audi, Mitsubishi, Kia and others can have worn or otherwise damaged spark plug threads. Sometimes the failure is caused by human error, like starting the spark plug crooked and cross threading it. Sometimes the spark plug hole threads are damaged by not tightening the spark plug enough which leads to loosening and vibration which eventually blows the spark plug out of the hole taking some threads with it. Even over-tightening spark plugs can stretch the threads causing damage. Whatever the cause of the spark plug threads getting damaged, we’ve got the kit that will save the cylinder head.
