• The secondary air injection pump (also referred to as a smog pump or SAI pump) is responsible for lowering the number of carbon emissions that come out of the tailpipe of a vehicle. This is necessary since a vehicle engine is never 100% efficient in the combustion process.
• Secondary air injection pump failure is easy to recognize. If you notice at least two of the following symptoms, you need to get it serviced right away: 1) Check Engine Light; 2) Failed Emissions Test; 3) Weak Acceleration; 4) Engine Stalling; 5) Low Idle
• Package includes 1x smog air pump with 3x air pump mount. Please confirm that the OE part number and the applicable model match your vehicle before placing the order. If you are not sure if our products are compatible with your model, please contact us.
