Review on Bapmic 11727553056 Secondary Air Injection Smog Pump: Optimized for BMW 3 Series E46 323i 325i 328i 330i by Darnell Murphy

Revainrating 5 out of 5

Worthy alternative to OEM

Bolted and connected just as expected. Slightly louder than the OEM unit it replaced (to death). In any case, it only runs for 30-45 seconds on a cold start, so the noise isn't a problem for me. Much better than the OEM part in my opinion. Even if it takes twice as long.

Pros
  • Sturdy construction
Cons
  • Ugly packaging
