cleaning engine bay???
Personally I have the MSD opti and I rinse it with the hose everytime I wash the engine bay. I believe the MSD is sealed very well and it has never missed a beat so I will continue to do it. I also try to dry off what I can with a rag and then like I said go out and drive for like 15-20 minutes to make sure everything is completely dry. Here is what I end up with, I just gotta get the intake manifold black, polish the fins, then polish the TB.
