TRASK Assault Charge High-Flow Air Cleaner — Round, Black – 91-04, 06-22 Sportster

Assault Charge high-flow air cleaner delivers improved airflow and throttle response, dyno-developed and tested for measurable performance gains. 🚀

The unit uses a precision-machined backing plate with a hidden integrated breather system and a clear outer cover for quick inspection of the filter element. 🔍

A snap-in velocity stack improves airflow; an optional velocity stack (part number 1010-2218) upgrades the stock opening to 58 mm for additional tuning flexibility. 🔧

The high-flow filter element is reusable — simply clean and re-oil to restore performance, and the design supports straightforward installation. 🧰

Dyno testing validates the design across multiple setups, and the kit accommodates common tuning upgrades for riders seeking increased engine breathability. 🔁
