Auxiliary Air Valve Porsche Auxiliary Air Valve 0280140209 Part No: 91160610204Quantity: Invalid Quantity. Special Notes Put an end to erratic fuel injection. We carry Bosch replacement air valves. The auxiliary air valve provides for a slightly fast idle for a cold engine. It does this by allowing more air in bypassing the closed throttle valve. It does not however change the fuel/air mixture because the air entering the auxiliary air regulator has already been measured by the air flow meter. It just lets some air bypass the throttle body for a fast idle to help keep the cold engine running. There is a rotary valve in the housing with one hole in it. This valve is connected to a bimetallic strip. When the engine is cold the bimetallic strip rotates the valve so that the hole is aligned with the two air hoses--air can pass through the valve. When the ignition is turned on a heataing element begins to warm the bimetallic strip. As the strip warms it beins to close the valve. From the coldest the valve will close in about 8 minutes. When fully warm no air will pass through the valve. Tech Tip! The regulator can be tested by blowing through it with the engine cold--air should pass freely. When the engine is warm you should not be able to blow through it. Bosch # on Part :0280140209 / Please Verify Application Notes Put an end to erratic fuel injection.
