Proflow's SuperMax fabricated intake manifolds are cost effective and performance filled! These black powdercoated intake manifolds feature 3mm (1/8") thick 6061-T6 sheet aluminum construction with 100% TIG welds for strength and durability. The tapered intake runners are designed to increase air velocity to evenly distribute airflow to all 8 cylinders, improving throttle response and providing consistent volumetric efficiency for your engine. There is also provision for a standard GM LS map sensor to be mounted on the rear of the plenum.

SuperMax LS manifolds are intended for maximum performance applications and will work best with upgraded engine components and hardware, such as upgraded camshafts and cylinder heads.

The EFI Hi-Ram style versions can be purchased with a 92mm or 102mm throttle body opening and come complete with fuel rail kits ready to go. The Tunnel Ram intakes have both 4500 and 4150 flange bolt patterns for carburettors or throttle bodies. All Proflow LS intake manifolds are avaliable in both LS1/LS2/LS6 and LS3/L92 intake port openings.
