Description:

The BMC Performance Air Filter is designed to deliver a noticeably higher airflow compared to conventional paper filters. By utilizing advanced motorsport technology from Formula 1, BMC achieves optimal air pressure balance to support maximum engine performance. When replacing the stock filter, you benefit from increased power output, faster throttle response, and improved filtration efficiency.

Thanks to the innovative "Full Moulding" production process, the filter consists of one solid piece of soft rubber with no welded joints, reducing the risk of breakage and ensuring long-term durability. The red filter frame, characteristic of BMC, combines reliability with a distinctive design.

Each filter is carefully constructed using epoxy-coated alloy mesh to resist fuel vapors and corrosion. The multi-layer cotton gauze, impregnated with low-viscosity oil, ensures excellent permeability and filtration performance — delivering enhanced airflow while maintaining superior engine protection. This makes the BMC Performance Air Filter the ideal upgrade for drivers seeking both performance and longevity.
