K&N BM-1019 air filter for the BMW S1000RR (2019-2020) only. Direct-fit, washable and reusable - no trimming, no adapters, no compromises.

• High-flow cotton gauze - increases airflow while retaining OEM-level filtration
• Clean and re-oil for life - no recurring filter costs, just proper maintenance
• Drop-in replacement - fits the stock airbox exactly; no tuning required for stage 1 or fast road use
• Track-day proven - handles heat and throttle snaps without flow restriction or oil migration

Not for earlier or later S1000RR models. Not a universal fit. Not an OEM replacement - it’s a performance upgrade that works as intended, straight out of the box.
