S&S Cycle Stealth Air Cleaner Kit with Carbon Fiber Cover - 170-0525B - Harley-Davidson

The S&S Cycle Stealth air cleaner kit with carbon fiber cover is an intake upgrade for Harley-Davidson and V-twin riders who want a cleaner, more aggressive look under the tank and a freer-breathing intake. It is a direct bolt-on kit built around a carbon fiber cover paired with a high-strength synthetic polymer backplate.

Riders choose this kit for its airflow and thermal design. The inlet is radiused and uses an S&S stinger to deliver a stated 38 percent increase in airflow, which supports more responsive throttle behavior. The polymer backplate is designed to reduce heat transfer into the intake air, so the engine receives cooler, denser air for more efficient combustion.

The carbon fiber cover is lightweight, corrosion resistant, and gives the kit a race-inspired appearance. The filter element is washable and reusable, which helps keep long-term service simple. The kit is designed for straightforward, direct installation and pairs well with other performance upgrades such as an exhaust system and tuning.

For off-road / closed-course race use only.
