I was out on the beach yesterday. There had been a very high tide because of a storm of the coast. The water wasn't very very deep but it splashed into my intake manifold and stopped me dead in my tracks. After about 5 minutes it started right up again. We drove very slowly and got out of the water. I thought I might add a Snorkel Kit for my 550 s4 but I can't find one on line. If anyone can tell where I might find one I'd appreciate it.
