Elevate both performance and style under your hood with the Moroso Racing Air Cleaner — a premium intake upgrade designed to optimize airflow, reduce stack height, and accentuate the appearance of your engine bay. This air cleaner kit is engineered for high-performance environments, yet accessible enough for serious street builds.
One of the standout features is the innovative radiused inlet design, which equalizes air pressure across the carburetor boosters for smoother, more consistent flow. Independently tested, it has delivered nearly a 10 hp gain when compared to running no air cleaner at all. With a low-profile build (about 2½ inches above the carburetor lip with a 3-inch element), it’s ideal for tight engine bays or lowered hoods.
Whether you’re after the sleek finish of the standard version or the premium look of the moroso gold air cleaner, this unit blends show-quality aesthetics with real performance potential. Built from high-quality materials and available in multiple finishes, it also includes PCV provision and a matching wing nut for a clean, finished install.
If you’re focused on airflow optimization, engine bay clearance, and dialed-in style, the moroso air cleaner is a smart choice. Pair it with your performance carb and intake manifold and you’ll get extra breathing capacity, reduced intake restriction, and a great-looking engine compartment. For those replacing an element or upgrading to a performance setup, this high-quality unit replaces the stock element while providing refined build quality and purpose-built performance ready out of the box.
