High-Flow Panel Filter Kit for BMW N63 & S63 V8 Applications
The BMC Air Filter FB866/04 is a precision drop-in twin panel filter kit engineered for BMW X5 and X6 V8 models, including 50i (N63) and X5M/X6M (S63). Built with BMC’s Full-Moulding red rubber frame and multi-layer oiled cotton gauze backed by epoxy-coated alloy mesh, it increases intake efficiency while filtering particles down to ~7 microns—tighter than typical OEM paper (~10 μm). Washable, reusable, and designed for an OEM-perfect seal in the factory dual airboxes.
