MWR Air Filter Triumph Bonneville / Thruxton

Performance air filter for the Triumph Thruxton / Bonneville & Scrambler replaces the OEM filter, and also the OEM filter cover, no permanent modifications needed. The OEM filter cover highly restricts the amount of airflow so MWR developed an air filter what must be installed without the OEM filter cover. Includes: air filter and  filter cage & four spacers. Remapping the ECU or a fuel control module is necessary with this air filter. Clean and re-oil filter at least once a year only with MWR filter oil and cleaner.
