BMS142/BMS143/BMS144 N54 Intake Filter Element for E82 E90 E92 E60 E89

Replacement filter element for the Burger Motorsports N54 intake system - not a generic OEM swap, not a bolt-on for stock airboxes. This is the exact filter used in the BMS142 (red), BMS143 (white) and BMS144 (blue) kits.

Designed for owners running stage 1, stage 2, fast road or track day N54 builds on E82 135i, E90/E91/E92/E93 335i/335is, E60/E61 535i, E89 Z4 sDrive35i. Fits only the BMS intake; no compatibility with stock housings, Dinan, Active Autowerke or other aftermarket intakes.

• N54-specific - built for high-flow, high-boost duty on N54 engines, not N55, B58 or S55
• Matches BMS part numbers BMS142, BMS143, BMS144 - colour-coded, same spec, same filtration
• Required for decats, aggressive maps, or sustained track use where airflow and heat soak matter
• No tuning needed - drop-in refresh for existing BMS intake users
• Not for daily driver 'OEM plus' or show car fitments unless you already run the full BMS system
