MWR AIR FILTER ADJUSTMENT KIT (HE & RACE ONLY) - SKU: MWR-500

MWR Air Filter Adjustment Kit for HE and Full Race filters.

Includes four springs, four bolts, and four locknuts. The adjustable plate helps guide incoming air and fuel from the upper injectors to improve high-speed throttle response, acceleration, top speed, combustion efficiency, and cylinder-to-cylinder balance.

MWR reports possible top-speed gains of 4–5 mph in race-team testing. Fuel tuning is required; adjustments vary by motorcycle, airbox design, filter position, injector and velocity-stack spacing, and whether variable velocity stacks are fitted.

Full Race basic setting: front 26 mm, rear 12 mm. Adjust the rear no more than 2 mm at a time. Lowering the plate to the minimum 9 mm height can reduce intake noise by approximately 2–3 dB for noise-restricted track days.

Important: This adjustment kit is intended only for compatible MWR High Efficiency and Full Race filters. MWR advises against using it with MC-110-05HE, MC-010-09HE, MC-050-08HE, MC-100-09HE, or MC-110-10HE because no performance benefit is expected.

Ducati 1199 Panigale: Individual-cylinder fuel adjustment is required. The standard and Corse ECUs do not provide this capability, so a suitable aftermarket fueling device is recommended.
