Air Injection System: Description

The air injection system injects fresh air into the exhaust manifold to help complete combustion. The additional oxygen enables the exhaust gases to burn more completely and lower emissions. The system includes an air filter, air pump, relief/diverter valve, air shut-off valve, check valve, and air injection manifold.
