6-Cylinder Air Injection

The pulse-air air injection system consists of check valves, control valves, control valve solenoids and various lines and hoses. Air is injected either at the front exhaust pipe or the catalytic converter depending on engine operation. The injection of air into the exhaust system helps to complete the combustion of unburned gasses. For additional information, see "Jeep Pulse-Air Injection System" article in this section.
