Proflow RPM AIRMax Intake Manifold – Aluminium, Black, Square Bore, Chev Big Block Oval Port | PFEM7561-BK

Proflow RPM AIRMax Intake Manifold – PFEM7561-BK

Engineered for serious big block performance, the Proflow RPM AIRMax intake manifold delivers a cooler, denser air/fuel charge all the way to the cylinder heads — exactly where it counts on the strip or the street.

Key Features

• AirMax open-plenum design separates runners from lifter-valley heat, keeping the charge cooler for improved combustion efficiency
• Tuned runners shift the power band 1,000 RPM higher than the original AirDual manifolds — optimised for 1,500–6,500 RPM
• Square bore carburettor flange for broad carb compatibility
• Cast from high-quality aluminium for strength-to-weight advantage and corrosion resistance
• Black finish for a clean, purposeful engine bay look
• Designed specifically for Chevrolet Big Block oval port cylinder heads
