Trask Assault Charge Air Cleaner – Harley Twin Cam (TBW) High-Flow Intake

U.S. Pat. No. 10,876,503 B2

This Assault Charge Air Cleaner is engineered for late Twin Cam applications ( Throttle by wire), including '08 to '16 Harley-Davidson FL models, '12 to '15 Harley-Davidson CVO Softails, '16 to '17 Harley-Davidson Softails, and the '16 to '17 Harley-Davidson Dyna Low Rider S. These models 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.

With a magnetic velocity stack, oversized filter, and a billet backing plate featuring a concealed integrated breather system, this air cleaner replaces the stock unit and brings a sharper, more responsive feel to the Twin Cam platform. Independent testing has shown gains of about 8 horsepower, placing it among the highest-performing options for this engine series.

If you are building a stronger late-model Twin Cam or simply want a durable intake with real flow advantages, this kit fits the platform perfectly.

Reverse Cut comes as a Matte Black base w/ Raw cutouts

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.
