Trask Assault Charge High Flow Air Cleaner For Harley
Trask Assault Charge: The Clear Leader in High-Output Induction
The Trask Assault Charge High Flow Air Cleaner represents the 2026 pinnacle of “Performance Bagger” engineering. For the rider who values transparency—literally—this air cleaner offers a striking forward-facing design protected by a high-impact plexiglass cover. This isn’t just a styling exercise; the Assault Charge is built to feed high-displacement Milwaukee-Eight and Twin Cam engines the massive volume of air they require for maximum combustion. By positioning the intake away from the radiant heat of the cylinders, the system captures cooler, oxygen-rich air, resulting in the immediate throttle response and significant mid-range torque gains necessary for aggressive 2026 riding. Whether you’re hitting the local drag strip or touring the open road, the Assault Charge delivers the secure, industrial-strength utility that has made Trask Performance a household name in the V-Twin world.
Industrial Engineering and Precision Fluid Dynamics
What sets the Trask Assault Charge apart in the 2026 marketplace is the internal velocity stack architecture hidden behind its clear window. The intake tract is precision-contoured to eliminate “dead spots” and air turbulence, creating a laminar flow that helps your EFI system perform with surgical precision. The massive high-flow filter is constructed from a premium synthetic material that is both washable and reusable, ensuring it remains a permanent fixture of your bike’s performance setup. Supporting the unit is a CNC-machined billet aluminum backing plate that features an integrated breather system, routing engine gases internally for a clean, hose-free aesthetic. Available in show-quality chrome or a tactical matte black finish, every component is over-engineered to withstand the high-vibration environment of a performance Harley-Davidson through the 2026 season and beyond.

Expert Installation & Performance Advice
As specialists in high-performance V-Twin components, we recommend the Assault Charge for its combination of visual “wow factor” and mechanical efficiency. Pro Tip: Due to the massive increase in airflow, we highly suggest a Stage 1 ECU recalibration using a Dynojet Power Vision or Vance & Hines Fuelpak to ensure your 2026 air-fuel ratios remain optimal. Installation Note: When mounting the plexiglass cover, use the included vibration-dampening washers and do not over-torque the hardware to prevent stress-cracking. Maintenance Note: To clean the clear cover, use only a dedicated plexiglass cleaner and a soft microfiber towel; avoid ammonia-based window cleaners which can fog the material over time. Safety Note: Periodically check the mounting hardware during your 2026 service intervals, as the forward-facing position is subject to significant wind resistance at highway speeds.
