Enhance your Harley Davidson touring bike's performance with the S&S Cycle 17-23 M8 Touring and 2018-2023 Big Twin Stealth Air Cleaner Kit, Part Number 170-0598A. Crafted from high-strength synthetic polymers typically used in high-performance automotive intake manifolds and premium handgun bodies, this air cleaner backplate offers superior mechanical strength, thermal stability, and chemical resistance. Its design features a radiused inlet and a unique S&S stinger, which together facilitate smoother and faster airflow, contributing to increased horsepower and overall engine efficiency. The increased filter area and a taller, high-flow filter (available as part number 170-0127) provide approximately 38% more airflow, resulting in cooler, denser intake air that improves cylinder filling and engine responsiveness. This kit is engineered to reduce heat transfer to the intake air, further optimizing performance. The washable filter element simplifies maintenance, and the overall design ensures easy installation without the need for extensive modifications. As a 50-state legal product, it is compliant with emissions regulations and exempt from tampering regulations under CARB EO# D-355-30. Whether you're upgrading for performance or style, this air cleaner kit is a reliable choice for compatible Harley Davidson touring models and Big Twins from 2017 through 2023, offering improved airflow and engine efficiency while maintaining legal compliance.
