K&N Replacement Air Filter for Aprilia RSV4 / Factory / R (2009–2014) – AL-1010

The K&N AL-1010 replacement air filter is engineered to meet and exceed the noise and emissions standards demanded of road-legal motorcycles, while simultaneously unlocking the full breathing potential of the Aprilia RSV4 airbox. Compliant with OEM electronic systems straight out of the box, it slots in exactly where the standard filter sits — no modifications, no mapping changes, no compromises to homologation.

Key Features

• Direct OEM replacement: fits the Aprilia RSV4, RSV4 Factory and RSV4 R (2009–2014) without any system modifications or ECU recalibration.
• Fully compliant with noise and exhaust emissions regulations, making it a road-legal upgrade with no MOT or technical inspection concerns.
• Optimised airflow through the factory airbox delivers measurable gains in horsepower and acceleration by maximising the efficiency of the existing intake system.
• Washable and reusable design means a single filter outlasts the life of the engine — no repeat purchases, no landfill waste.
• Extended service intervals of up to 80,000 km between cleaning cycles, slashing routine maintenance time and cost.
• Seamlessly compatible with all OEM vehicle electronics and sensors — no adapters, no signal interference.

Engineering & Build Quality

K&N's multi-layer oiled cotton gauze filtration medium is the defining technology here. It captures harmful contaminants that would otherwise cause engine wear, while flowing significantly more air than a paper element ever could. The cotton gauze is sandwiched between pleated wire mesh screens for structural rigidity under the high-velocity airflow generated by the RSV4's 999 cc V4, ensuring the filter holds its shape even under sustained hard acceleration on track or at high road speeds.

Unlike paper filters that degrade progressively and must be discarded, the AL-1010 is simply cleaned with K&N's own filter care kit, re-oiled, and refitted. The engineering cost is front-loaded into the initial purchase; from that point forward the filter effectively pays for itself with every service interval it replaces.

Road & Track Use

For RSV4 owners who split their riding between public roads and circuit days, the AL-1010 offers a rare combination of regulatory compliance and genuine performance benefit. It keeps the airbox, airflow sensors and OEM electronics completely undisturbed, which matters on fuel-injected machines where the ECU relies on accurate mass-air readings. There is no need to remap, rejet or adjust anything — fit it and ride.
