Hi, my name is ***** ***** TAC, thermostatic air cleaner is mounted to the airfilter housing, there will be a large flexible tube going from the airfilter housing down to the exhaust manifold, this allow warm air to come off the exhaust manifold when it is cold, and this aids in reducing emmissions, it is vacuum operated, and opens when its cold and closes when its warm, below is a diagram of it, the 67 is the hot air tube and 55 is the TAC valve,Tim
