4 mm Air Pump Plates for Subaru petrol engines

The air pump is not required in many racing classes and deleting it saves some weight, complexity, and won't interfere with the rest of the exhaust or engine management system (deleting the air pump may require special programming in the ECU, a simulator, or a stand-alone engine management system).

Note: removing your SAI system will cause check engine codes. Proper programming is required to eliminate these codes.
