Radium Fuel Filter Kit | 2001-2006 BMW M3 E46 (20-0429)

The S54's injectors deserve better filtration than a twenty-year-old canister provides.

The Radium Engineering Fuel Filter Kit for the 2001-2006 BMW M3 (E46) modernizes the delivery path: a Radium high flow fuel filter with chassis-specific mounting replacing the factory filter arrangement, putting serviceable injector-grade filtration inline on the S54's feed. The delivery insurance every fuel system upgrade should include.

What You'll Feel

• Injector protection through serviceable, high flow filtration
• The aging factory filter arrangement retired for hardware that services on your schedule
• E85 readiness through the media options

Features

• Radium high flow filter with chassis-specific mounting
• Serviceable element architecture; media per Radium's kit configuration

The Details

Fuel filters age invisibly, flow degrading behind sealed steel until pressure sags under demand, and the serviceable architecture ends the mystery: the element inspects, cleans or replaces per its media, and the housing serves for the car's life. Radium's media split applies, with microglass capturing to the Bosch Motorsports standard and working well with E85, replacing at intervals, while stainless cleans and reuses indefinitely. Pairs naturally with the 20-0884 pump install kit upstream and the S54 rail downstream, completing the delivery path end to end.
