This is an OEM MAHLE fuel filter that removes dirt and other particle contaminants from your fuel.

A clogged fuel filter makes it difficult for your engine to get all the fueling it needs. Filters commonly clog from a deteriorating gas tank, bad fuel, or other debris in the fuel system. A fresh fuel filter addresses many fuel related problems including surging, stalling, cold start issues, and poor performance under a variety of conditions.

Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. Finding a way to measure your fuel pressure is not always the easiest thing to do. Race German wanted to make your life just a little easier with this in-line fuel pressure adapter. This simple solution allows you to splice into your rubber fuel feed line hose and attach a 1/8NPT pressure sender. This would be great to run a fuel pressure gauge, or give you a way to temporarily test your pressure for troubleshooting issues, either way you can't go wrong. *Does not include pressure sender.
