The first place to look at for fuel supply and lean condition faults is the fuel filter. It's not hard for contaminants, dirt, and dust to find its way into your fuel system. Even rust can form in the tanks of some cars and that debris gets transferred through the system until eventually reaching the filter. There's nothing wrong with the system - the filter is doing exactly what it's supposed to do! But regular replacement of the fuel filter will ensure plenty of fuel is available for the engine to make power with. Is there a power gain from a fuel filter? No, but there is power restoration. The fuel filter is easily accessible on most cars and replacement is straight forward.
This is an OEM replacement fuel filter. BMW recommends changing the fuel filter every 20,000 miles to keep your fuel injection system clean, a must for every tune-up. Fits 2001-2006 M3 (E46) and 2001-2002 MZ3 Roadster & Coupe (S54 engine). We recommend replacing the aluminum crush ring #07119963129 while replacing the filter.
