K&N BM-1010 Drop-In Air Filter for BMW S1000RR K46 (2009-2018)

The K&N BM-1010 is a precision-engineered drop-in replacement air filter built specifically for the BMW S1000RR K46, covering model years 2009 to 2018. Constructed from multiple layers of oiled cotton gauze within a durable wire mesh frame, it delivers measurably higher airflow than the factory paper element while maintaining the rigorous filtration standards your engine demands.

Key Features

• Direct OEM replacement — fits the stock airbox without any modifications to the intake system or electronics
• Multi-layer oiled cotton gauze construction maximises airflow through the airbox, liberating additional horsepower and improving acceleration response
• Washable and reusable design eliminates the recurring cost of paper filter replacements over the life of the motorcycle
• Extended service intervals of up to 80,000 km between cleaning cycles, reducing maintenance downtime
• Fully compatible with all factory vehicle electronics and fuel mapping — no ECU remapping required
• Protects the engine against harmful contaminants including dust and fine sand particles
• Compliant with applicable noise and emissions regulations

Premium Construction, Lasting Performance

Where a disposable paper filter degrades over time and increasingly restricts airflow as it loads with debris, the K&N BM-1010 is built to last the life of the engine. The layered cotton media is treated with specially formulated K&N filter oil, striking the balance between maximum particle capture and minimum restriction. The surrounding wire mesh cage provides structural rigidity that prevents collapse under hard acceleration — exactly the kind of riding an S1000RR is made for. When the filter eventually needs attention, a K&N Recharger cleaning kit restores it to factory specification in minutes.

Airbox Optimisation Without Compromise

The BM-1010 is dimensioned to fill the S1000RR K46 airbox volume correctly, so the factory airbox acts as an efficient plenum rather than a restriction. The result is a more immediate throttle response and stronger mid-range pull — noticeable on road and track alike — without sacrificing the acoustic or emissions compliance required for street use.

Fitment & Compatibility

The K&N BM-1010 fits the following motorcycle:

• BMW S1000RR (chassis code K46) — model years 2009 to 2018

Installation is a straightforward like-for-like swap requiring no airbox modifications, no additional brackets, and no changes to the OEM fuel injection or engine management system.
