I've searched, and haven't found a good answer. Maybe that is because there is no good answer.
I've had a '03 VVT head on my car for several years. I use GM truck coils, with a custom bracket, and Magnecore wires.
I have a problem with water buildup in the spark plug holes after washing the engine bay. Major misfiring, until I vacuum out the water. Super annoying.
So far it has only happened after engine bay cleaning, but I'm worried it may happen on a rainy day with puddles as well.
Has anyone found a spark plug boot(s) that fits the VVT head? It appears that it would need two different types in order to fit properly.
