Radium FPR and Fuel Filter Kit, BMW E46 M3

The Radium Engineering 20-0932 FPR and Fuel Filter Kit is an OEM fuel filter replacement and fuel pressure regulator solution for the BMW E46 M3. Designed to replace the factory fuel filter with a larger, less restrictive unit, this kit reduces stress on the fuel pump by lowering pre-filter pressure — resulting in less current draw, lower fuel temperatures, and increased fuel flow capacity.

Two selectable filter elements are available: a 10 Micron Stainless reusable element (20-0932-03) or a 6 Micron Microglass disposable element (20-0932-05). Both are compatible with alternate fuels including methanol, ethanol, and E85.

Key Features

• OEM fuel filter replacement — larger and less restrictive than the factory BMW filter
• Reduces pump stress — lower pre-filter pressure means less current draw and lower fuel temperatures
• Selectable filter elements — choose 10 Micron Stainless (reusable) or 6 Micron Microglass (disposable)
