Contrary to popular belief, BMW does not make their own Air Pump. A third party actually manufactures and sells these factory Air Pumps directly to BMW. BMW then installs these Air Pumps in your 540 at the factory assembly line. We sell the same OEM factory Air Pumps that you would buy directly from the BMW dealer, but at a much more affordable price!

We also manufacture our own version of every OEM Air Pump to exact factory specs. The Buy Auto Parts brand Air Pumps look, fit, and perform the same as the factory BMW Air Pumps. Because you are buying directly from the manufacturer, you are able to buy them at just a fraction of the price!

Anytime you call Buy Auto Parts you will speak with one of our Air Pump specialists located in the USA. We are proud to provide industry leading customer service and warranties. Our customers love working with us and continue to show us their appreciation by leaving us outstanding online reviews.

If you are not able to find the BMW 540 Air Pump from our online catalog or if you need any technical assistance, speak to our sales and support team through our toll free support lines 1-888-907-7225. You can also send emails to [email protected] for any clarification regarding the car parts.
