BMC FBTW85-140P Twin Air Universal Conical Air Filter 85mm ID / 140mm H Polyurethane Top

The BMC FBTW85-140P is a universal conical performance air filter featuring a Twin Air (TW) design with both central and lateral airflow, an 85mm inner diameter inlet, and a 140mm height with a polyurethane (plastic) top. Engineered in Italy by BMC — Boldrini Motori e Componenti — this filter is designed for direct-induction custom intake applications where the factory airbox has been removed.

The TW (Twin Air) design delivers airflow from both the sides and the center of the filter cone, maximizing intake volume compared to single-inlet designs. The characteristic red rubber base collar provides a heat-resistant, deformation-proof seal that stands up to high engine bay temperatures and mechanical stress. BMC's advanced cotton gauze filtration media is washable and reusable — simply clean, re-oil, and reinstall — making this a long-term, cost-effective performance upgrade over disposable paper filters.

Key Features:

• Twin Air (TW) configuration — dual central and lateral airflow for maximum intake volume
• 85mm (3.35") inner diameter inlet opening for a secure clamp-on fitment
• 140mm (5.51") overall height conical filter body
• Polyurethane (plastic) top cap for lightweight, durable construction
• Special filtration mesh supports engines rated up to 700 HP without filter deformation
• Heat-resistant red rubber base collar resists engine bay temperatures and stress
• Washable and reusable cotton gauze media — clean, re-oil, and reinstall
• Universal fit — compatible with most engines after airbox removal
• Sourced from BMC, a Bologna, Italy-based manufacturer with decades of motorsport heritage

The BMC FBTW85-140P is an ideal choice for custom cold air intake builds, turbo inlet plumbing, or any performance application requiring a high-flow conical filter with an 85mm inlet. Not CARB compliant — not legal for sale or use in California.
