FMR's High Flow Intake
High Flow Intake
Designed to replace the restrictive airbox intake on the four stroke models. This billet unit offers maximum air flow. The stock carburettors need more airflow to make more power, especially on modified or piped motors. Works much better than modifying or drilling holes in the stock airbox. Beautiful billet aluminium unit with Hot Seat logo easily installs in minutes. Some rejetting is required.
