{"product_id":"bmc-fm903-04","title":"BMC Replacement Air Filter Kawasaki ZX-10 R\/RR (2016-2026) FM903\/04","description":"\u003cp\u003eBorn from decades of motorsport heritage, the BMC FM903\/04 replacement air filter brings genuine race-derived filtration technology to the Kawasaki ZX-10 R and ZX-10 RR. Its distinctive four-layer cotton gauze construction — steeped in low-tack oil and wrapped in a protective aluminium mesh — is the product of the same engineering discipline that has made BMC a fixture in MotoGP and World Superbike paddocks. For ZX-10 R riders who demand more than the standard paper element can offer, this is the definitive upgrade.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFour-layer oiled cotton gauze delivers higher airflow than the OEM paper filter, reducing pressure drop and freeing up engine performance across the rev range.\u003c\/li\u003e\n\u003cli\u003eAluminium mesh surround shields the cotton medium against fuel vapour and oxidation, preserving filter integrity over many thousands of kilometres.\u003c\/li\u003e\n\u003cli\u003eRubber frame eliminates the risk of cracking or distortion, ensuring a consistent, leak-free seal within the airbox every time.\u003c\/li\u003e\n\u003cli\u003eWashable and reusable design means one filter can last the lifetime of the motorcycle — a cost-effective and environmentally responsible alternative to disposable paper elements.\u003c\/li\u003e\n\u003cli\u003eEnhanced dirt absorption capacity keeps contaminants away from the engine, combining superior filtration efficiency with the airflow gains that define BMC's reputation.\u003c\/li\u003e\n\u003cli\u003eDeveloped and validated to international test standards, guaranteeing the quality and consistency expected from a premium Italian filtration brand.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eRace Heritage, Road Refinement\u003c\/h2\u003e\u003cp\u003eBMC — Bmc Bologna Motor Company — built its name supplying air filtration to factory racing teams where marginal gains matter most. The FM903\/04 carries that lineage directly into a road-legal form factor, designed as an exact drop-in replacement for the standard ZX-10 R\/RR airbox. There is no jetting, no mapping change, and no airbox modification required: the filter simply replaces the OEM element and immediately allows the engine to breathe more freely.\u003c\/p\u003e\u003cp\u003eThe four-layer cotton construction is the foundation of BMC's performance advantage. Each layer is precision-woven and individually oiled with a low-viscosity, low-tack compound that traps particulates without impeding airflow. Compared with a single-layer paper filter, the result is a measurably higher air volume reaching the throttle bodies at any given engine speed — translating to sharper throttle response and a more linear power delivery that ZX-10 R riders will notice immediately.\u003c\/p\u003e\u003ch2\u003eBuilt to Last\u003c\/h2\u003e\u003cp\u003eThe aluminium mesh cage that surrounds the cotton medium is more than a structural element. It actively resists the fuel vapour and moisture that accumulate inside a high-performance airbox, preventing the oxidation that degrades lesser filters over time. Combined with the rubber sealing frame — which absorbs vibration and maintains its shape even under sustained high-rpm use — the FM903\/04 is engineered to outlast multiple service intervals without any loss of performance. When performance does taper, the filter is simply cleaned with the appropriate BMC washing kit, re-oiled, and reinstalled.\u003c\/p\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cp\u003eThe BMC FM903\/04 is a direct OEM replacement air filter for the following Kawasaki models:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eKawasaki ZX-10 R — 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003cli\u003eKawasaki ZX-10 RR — 2016, 2017, 2018, 2019, 2020, 2021, 2022, 2023, 2024, 2025, 2026\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eNo airbox modification is required.
