Radium Engineering FPR and Fuel Filter Kit (With Filter) - BMW 3-Series (E46)
This bolt-in Radium Engineering kit replaces the factory fuel filter and fuel pressure regulator on the 2001-2006 BMW E46 M3 using the original fuel lines. The larger, less restrictive Radium filter lowers pre-filter pressure, reducing pump current draw and fuel temperature while increasing available flow.
The OEM regulator is swapped for a Radium RA-series multi-port FPR with tool-less adjustment: turn the knob and detents give roughly 1psi per click. Choose a 6-micron microglass element (SKU 20-0932-05) or a reusable 10-micron stainless element (SKU 20-0932-03) from the variant selector.
Note: Uses the factory fuel lines and nothing else is required for installation. Suitable for all petrol types plus methanol, ethanol and E85. Installation by a professional is recommended.
