The TWIN AIR Standard Air Filter is designed for select Honda motocross and off-road motorcycles. Its dual-bonded foam construction filters even the smallest dirt particles while allowing more airflow than two separate-layer filters, based on flow bench testing. The filter is slightly smaller than stock to simplify installation and removal while increasing dead air space around the filter for performance.
A flat foam sealing ring provides a secure seal against the airbox, including in demanding riding conditions. Distributor part number: 150233. Manufacturer part number: 150233.
