Suppose you wanted (for some reason) to temporarily reconnect the AIR system on your car and wanted to avoid the hassle of installing it all in the original location. You can. It is very easy if you install the exhaust AIR pipes facing forward and mount the AIR solenoid on the front of the passenger-side head (instead of the rear of the driver-side head). You can use most of the original plumbing but you need to extend one air hose (with ¾ inch heater hose) and two vacuum lines. To avoid the stock rear vacuum connection PITA, I inserted a tee in the PCV line between the PCV valve and the intake manifold. A picture of my temporary AIR system is attached.
