TRASK Assault Air Cleaner - Black - EFI - Harley-Davidson '99-'17 - TM-1021BK

This Assault Charge Air Cleaner package is built for the 99 to 07 Twin Cam FL models, 00 to 15 Softails, and 99 to 17 Dynas. Evolution models with CV-style carburetors are also compatible, while Evolution models fitted with Mikuni carburetors require the Trask Mikuni Air Cleaner Adapter (DM-1797). These platforms benefit noticeably from improved intake efficiency, and this system delivers both a cleaner visual profile and a measurable increase in performance.

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.

Please note that the Assault Charge Air Cleaner recirculates head breather pressure back into the throttle body, similar to the stock Harley-Davidson air cleaner setup. For those wanting to vent head pressure externally, the Trask External Breather Kit is available for purchase.
