NOTE:
- If you’ve already experienced engine stalling, poor acceleration, and a check engine warning light, then you need to have the secondary air injection pump checked out immediately.
- The function of the secondary air injection pump is to allow air to be pumped into the exhaust, helping to put enough air into the mixture to burn when the engine fires again, which can make fuel burn more fully. When the secondary air pump has the following faults: the fault light is on, and the fault code appears. This means you can replace the secondary air jet pump.

This was plug and play and worked in my 2003 330ci (M54). Despite complaints that this doesn't have a filter in it, I opened mine up and verified that it did ship with a filter inside. It's a bit cheap feeling and louder than the factory pump, but it works. I can't comment on longevity, but it's been going for a few weeks without issue.

I installed this in my 2002 325xi Touring. The comparable BMW branded part was $450+. The part is very easy to swap out, so if there is a problem I can buy another one and still be money ahead. As others have mentioned, it is noisy. It only runs a few minutes on startup anyway.

Long story short is it worked, corrected the trouble codes, but it is very loud when running so you will hear it. The good thing is it only runs for about 2 min on a cold day and you will know if it stops working when you dont hear anything! Build in trouble shooting.......

I've had 2 of these fail in a short period of time. The first one worked literally only for 1 week. Thankfully Amazon replaced it, at no charge, but the replacement only lasted 2 months ! Unfortunately the return period has passed, so I'm SOL on that $75. I won't be buying another one of these !Fair warning before you buy one !

Bolted and hooked up exactly as expected. Slightly louder than the OEM unit it replaced (prior to dying). It only runs for 30-45 seconds on a cold start anyway, so the noise isn't an issue for me.Absolutely a better deal than the OEM part in my opinion. Even if it only lasts half as long.
