Trask Assault Charge High-Flow Air Cleaner - Twin Cam

Gain a noticeable bump in airflow and throttle response with a performance intake, and the Assault system delivers both the look and the power riders expect. The high-capacity filter and magnetic snap-in velocity stack provide strong, consistent airflow, while the billet aluminum backing plate includes a concealed integrated breather system that installs cleanly in place of the stock air cleaner. This setup has been dyno-tested and ranked among the highest-flowing air cleaners available for Twin Cam models, often producing gains of around 8 horsepower.

For riders who want a proven performance upgrade with a look that never fades, this Assault Charge system is built specifically for the needs of these Twin Cam platforms.

Rain sock included in the box. Please check packaging thoroughly.
