Product Description

The BMC FM579/04 Performance Air Filter is engineered to replace the restrictive OEM paper element on select Kawasaki ER and Ninja motorcycles. Designed for riders seeking improved engine breathing and throttle response, this high-flow panel filter uses multi-layer oiled cotton gauze media to allow greater airflow while still providing excellent filtration. The enhanced airflow helps improve overall engine efficiency and performance without sacrificing protection against contaminants.

Constructed with BMC's full-molded one-piece design, the FM579/04 eliminates weak welded joints for increased durability. The epoxy-coated alloy mesh protects the filtration media from petrol vapors and humidity, while the washable, reusable design reduces the long-term maintenance cost. This filter drops directly into the stock airbox with no modifications required, making it a straightforward performance upgrade for compatible Kawasaki ER-4F, ER-4N, ER-6F, ER-6N, Ninja 400, and Ninja 650 R models. Coverage is confirmed through the listed model years; fitment for later generations including 2025 is unconfirmed at time of listing.
