The A.I.R. (Air Injection Reaction) System was included on \012California-emission equipped vehicles. The system is designed to \012provide additional oxygen to continue the combustion process after the \012exhaust gases leave the combustion chamber. The system begins with the \012outside air inlet, which is a short, L-shaped open-ended rubber hose \012running from the lower front passenger fender well into the canister. \012The black plastic round canister is located in the front passenger-side \012engine compartment, adjacent to the EECS (Evaporative Emission Control \012System) canister, which looks similiar, but the EECS canister has \012electrical connectors on the top. While the charcoal canister of the \012EECS is a sealed unit, the A.I.R. canister has a twist-off lid to access\012 the disposable filter. The inlet hose goes into the canister, air then\012 passes through the charcoal filter, and travels into the outlet hose \012(also made of black rubber), which then connects directly to a metal \012tube coming up the front of the engine. Please contact me if you need a\012 diagram or photos.
