Increased filter area, combined with a radiused inlet and unique S&S stinger allow smoother faster airflow for more power. The S&S Stealth air cleaner backplate is made from the same high-strength, advanced, synthetic polymers used in high-performance automotive intake manifolds and high-end handgun bodies! This material offers superior mechanical properties, thermal stability, and chemical resistance. Designed to reduce heat transfer to the intake air for more efficient induction.
