Secondary Air Injection Pumps
Reduce emissions and cold-start noise. Secondary air pumps inject fresh air into the exhaust to heat up the catalytic converter. We stock Pierburg and Bosch pumps for Mercedes, BMW, and VW to clear engine check lights.
- Emissions: Essential for passing smog tests and maintaining Euro standards.
- Operation: Replaces noisy, whining pumps that operate on cold start.
- Protection: Check valve failure often kills these pumps; we sell both.
The 28CarParts Advantage
Screeching noise on start-up? Your secondary air pump bearings are shot. Replace it with Pierburg for quiet operation.
