BMC 2017+ Kawasaki Z 900 Replacement Air Filter- Race

BMC Race Air Filter Kawasaki Z900 (2017+) | High-Flow Replacement

Boost your Kawasaki Z900 (2017+) performance with the BMC Race Replacement Air Filter. Engineered for maximum airflow, track-tested durability, and reusability.

Unlock maximum throttle response and peak horsepower on your inline-four with the BMC Replacement Air Filter - Race Version designed specifically for the Kawasaki Z900 (2017+).

Unlike standard paper OEM filters that restrict airflow to meet strict noise and general urban emissions standards, the BMC Race version utilizes a specialized multi-layered oiled cotton gauze with fewer cotton layers to maximize high-RPM air intake. Manufactured using BMC’s signature single-mold "Full Moulding" process, this filter is crafted without welded joints, eliminating structural weak points and preventing air leaks under high-pressure induction.

The cotton filtering element is encased in an epoxy-coated alloy mesh, making it impervious to atmospheric humidity and fuel vapors. Designed as a direct drop-in replacement for your factory airbox, the BMC Race filter delivers up to 33.5% more airflow than OEM filters—making it an essential performance upgrade for track days, aggressive street riding, ECU tuning, and aftermarket exhaust setups.

Best Uses

1. Track Days & Racing: Designed to deliver maximum air delivery during high-RPM demands on the circuit.
2. Aggressive Street Riding: Improves throttle intake response and acceleration across the powerband.
3. Tuned Engine Builds: Ideal pairing for motorcycles equipped with aftermarket full-system exhausts, slip-ons, or custom ECU remaps.

Features

1. Race-Spec Cotton Media: Features fewer layers of oiled cotton gauze than standard filters to allow extreme air volume directly to the throttle bodies.
2. Seamless "Full Moulding" Construction: Molded in one continuous piece without welded joints, preventing rubber stress fractures or failure over time.
3. Epoxy-Coated Alloy Mesh: Protects the internal filter material against humidity, corrosion, and petrol fumes.
4. Precision Factory Drop-In Design: Engineered to exact OEM dimensions for seamless installation into the stock Kawasaki Z900 airbox.
5. Washable & Regenerable: Fully reusable using BMC washing and oiling maintenance kits, eliminating the need for single-use replacements.

Benefits

1. Superior Airflow Rate: Delivers up to 33.5% higher airflow over restrictive OEM paper filters for maximum combustion efficiency.
2. Enhanced Power & Acceleration: Helps unlock additional horsepower and sharper throttle response throughout the rev range.
3. Long-Term Cost Savings: Reusable design means you clean and re-oil the filter rather than buying a new air filter every service interval.
4. Micron-Level Engine Protection: Traps impurities down to 7 microns, providing high filtration efficiency despite increased air volume.
5. Durable Airbox Seal: High-durability polyurethane rubber compound expands slightly under temperature to create an airtight seal inside the airbox.
