Trask Assault Charge High-Flow Air Cleaner – Raw Aluminum or Black

Performance Air Cleaner for Harley-Davidson Models

The Trask Assault Charge High-Flow Air Cleaner is built for riders who want both performance and precision engineering. Constructed from CNC-machined billet aluminum, this air cleaner features a hidden integrated breather system and a clear plexiglass outer cover that reveals the internal velocity stack.

Designed to increase airflow and throttle response, the Assault Charge helps your Harley breathe better and perform stronger. Each unit is dyno-developed and tested to deliver measurable horsepower gains while maintaining a clean, aggressive aesthetic. The reusable high-flow cotton gauze filter provides long-term performance—just clean and re-oil as needed.

Choose between Raw Aluminum for an industrial, race-inspired finish or Black Powder-Coated for a stealth performance look. Proudly made in the USA, this air cleaner brings the same performance principles Trask uses on the track to your street machine.
