Heads-up on cancellations & returns: if you cancel an order or return an item, you won't get back 100% of what you paid. We apply a 10% restocking fee, the outbound shipping is non-refundable, and we have to pass on Shopify / PayPal payment processing fees; these aren't returned to us when we refund you. International orders also lose on exchange-rate spread in both directions. If the original packaging is damaged or missing, a reboxing charge applies. For international orders specifically, if you refuse to pay our shipping invoice or supply a prepaid label after placing the order, the same deductions apply. We're upfront about this — please be sure of your purchase before ordering.

BM-1199 Performance Intake Filter for BMW R 1100 S 1999 to 2005
Give your BMW boxer twin the airflow it deserves with the BM-1199 high-volume intake filter. This premium cotton gauze panel drops straight into the factory airbox on the R 1100 S, replacing the restrictive paper element with a serviceable, oiled media that helps the engine breathe more freely for sharper response and a smoother pull through the revs. It is washable, reusable and built for long-term use, making it a smart upgrade for road riders and tourers who want dependable performance and real value.
In our workshop we run this filter on our own bikes and customer machines, and the feedback has been consistently positive. Expect a crisper throttle feel, a subtle induction note and the convenience of cleaning and reusing the same element rather than buying disposable inserts again and again.
Key benefits
- Direct-fit panel filter for the BMW R 1100 S airbox with no cutting or drilling
- Multi-layer oiled cotton media supported by wire mesh for excellent filtration and airflow
- Reusable design reduces waste and saves money over repeated paper filter replacements
