Bosch Fuel Filter - E46, Z3

Product Details

BMW recommends changing your vehicle's fuel filter every 20,000 miles to keep your fuel injection system clean. This filter made by Bosch, a well-known and respected OEM part supplier, is sure to do so and provide worry-free operation for many miles. 

E46s fuel filters are equipped with an integrated fuel pressure regulator, a unique design that makes skipping this service costly. A clogged fuel filter can lead to lower fuel pressure at the fuel rail's inlet, causing hard starting, hesitation, misfire faults, bank one and bank two lean mixture codes, and even stalling. A failing fuel pressure regulator can cause many similar symptoms.
