Kawasaki ZX250R/RR ’20-’25, ZX4R/RR ’23-’25 MWR Air Filter

High Efficient Air Filter
Designed for road race bikes, focusing on inlet noise reduction. This revolutionary filter design reduces intake noise while delivering more power. It has shown a reduction of up to 8db of intake noise compared to other sports filters. All inlets receive the same quantity of air, regardless of motorcycle speed or wind direction. Separate tuning for each cylinder eliminates the need for different fuel mappings. Regular cleaning and re-oiling with MWR air filter oil & cleaner are essential. Remapping the ECU or the Fuel Control Module is highly recommended.

Full Race Air Filter
Developed on the track, not just on a dyno but in real-life scenarios with bikes equipped with Dataloggers, ensuring ultimate performance. Protection is on par with the filters above but for a shorter duration. Similar to the High Efficient filter, all inlets receive the same quantity of air, regardless of variables like motorcycle speed or wind turbulence. Tuning each cylinder separately enhances both strength and smoothness, ultimately conserving tires and fuel. It's crucial to check the filter after each race weekend and use only MWR filter oil & cleaner. Starting each race weekend with a well-oiled filter is advised. This filter is not designed to reduce inlet noise. Remapping the ECU or the Fuel Control Module is highly recommended.
