Key features

• •Secondary Air Pump injects fresh air into the exhaust gas behind the exhaust valve in a short time, to help further oxidized of CO and HC in the exhaust gas of the engine , thereby reducing the emission of harmful substances in the exhaust gas of the automobile.
• •If the injection pump begins to fail, since it is a vital part of the emissions system, a fault code will be triggered. Sometimes, when pulling off the lower secondary air pipe, you may see water pour out. This is a sign that your pump is more than likely faulty. By simply replacing this pump, efficiency can be restored and there will be no worry about failing an emissions test.
