Slant Edge Air Cleaner Liquid Black

The Slant Edge Air Cleaner Liquid Black from PROFORM is a premium intake component engineered for enthusiasts and mechanics seeking improved engine breathing and a refined engine bay aesthetic. As a seasoned mechanic, I recognize this air cleaner as purpose-built for classic and modern muscle car platforms where intake flow dynamics directly impact carburetor efficiency and throttle response. The angled design isn't merely visual—it's engineered to optimize air velocity and reduce intake turbulence, qualities that matter when tuning for peak horsepower and fuel atomization.

PROFORM's slant edge geometry increases filter surface area while maintaining a compact footprint, allowing cleaner air delivery without sacrificing under-hood clearance on tight engine builds. The liquid black finish is durable powder-coated steel, resistant to heat cycling and engine bay corrosion—critical for street and strip applications where temperature swings and moisture exposure challenge lesser components. Measuring 14.7 x 5.1 x 14.85 inches and weighing 6.665 lbs, this air cleaner integrates cleanly into stock or modified intake manifolds without requiring extensive fabrication or adapter plates.

This component works best for builders running carburetor-fed engines—small-block Chevys, classic Fords, and similar platforms where original round air cleaners limit modern intake design. Installation requires only a standard gasket and studs; no special tools or modifications are necessary. If you're restoring a muscle car or optimizing intake flow on a street engine, the Slant Edge Air Cleaner Liquid Black delivers authentic styling paired with measurable breathing improvements that serious gearheads expect.
