BMC air filter for the Royal Enfield Himalayan 411 and Scram 411, a washable, reusable performance replacement for the stock filter. It is built to boost airflow, sharpen throttle response, improve mileage and reduce engine strain, using Italian filtration technology. The element is multi-layer, high-flow cotton gauze over a durable epoxy-coated alloy mesh, with improved filtration efficiency for cleaner combustion. It is a precision-fit OEM replacement that installs as-is, and it can be washed and reused for lifetime performance. The filter is a red cylinder of pleated cotton gauze with red end caps and an open, flanged inlet at one end.
