MCS Aircleaner Assemblies

27 products — part of all Aircleaner Assemblies

MCS aircleaner assemblies deliver a straightforward performance upgrade for a broad sweep of Harley-Davidson engines. The range spans CV-carburettor Big Twins and XL Sportsters from the Sixties onwards, through Keihin, Bendix and Tillotson carb platforms, and into Delphi-injected Twin Cam models. Each assembly replaces the restrictive factory air box to improve airflow and throttle response without requiring specialist installation. If you ride a carb-era or early fuel-injected Harley, MCS offers an accessible route to better breathing.
