i was just cleaning my air filter and i noticed there was a little bit of grimmy stuff that settled in the air cleaner box and i thought i better clean the whole air box while im at it. so when i was cleaning it i noticed a weird air deflector thingy in it. its not in the round part, but its in the tube where it connects to the rad support. its also but a silver tin looking hose hooked up to it. it looks like the hose is connected to the exhaust manifold or something. its weird. and where the hose hooks up to it, its got a valve or something in the air intake tube thing. can anyone tell me what it is? it looks like it blocks off the air from comming into my engine but what the **** would you want that for? anyone got any ideas?
