Don't worry about stuff flying in it,at least I don't. Unless you smoke and throw cigarette butts out your window you have nothing to worry about. Did you look at my post on 986forum about the update louvre(intake grill)? It's linked earlier in this thread check it out. Porsche redesigned the lower two "fins" so objects can't fly in. The snorkel was to lower the sound level for other foreign places,not to protect stuff from flying in.Gerry said:Nice drawing there, dude! thanks...I'll try that as soon as I get home. after pulling it out, can I just put a mesh screen behind the grill so other contaminants won't go in?
