Proflow’s new cast aluminum SuperMax+ Intake Manifolds are purpose-built for high-performance, forced-induction applications utilising a 102mm throttle body. Featuring a low-profile, 3-piece design inspired by our full CNC billet version, these manifolds deliver exceptional airflow for maximum top-end power.

With short runners and an increased plenum volume optimised through advanced Computational Fluid Dynamics (CFD), they excel in mid-to-high RPM ranges, making them ideal for turbocharged setups. Each manifold includes high-volume billet fuel rail kits equipped with AN8 ORB ports for seamless fuel delivery and 1/8" NPT nitrous ports tapped into each runner!

Available in both cathedral port (LS1) and rectangle port (LS2/LS3) configurations to suit your specific engine platform.

Features:

• Designed for both rectangle/cathedral port heads
• Radiused internal runners to promote smooth airflow
• Suits 102mm Bore LS throttle body
• Provision for GM LS2/LS3 MAP sensor
• Includes billet fuel rails, mounting hardware and gaskets
• 4x vacuum ports located on the rear of the plenum
• Stainless Steel bolts used throughout including grade 12.9 mounting bolts
• Runner assemblies sealed with CNC machined O-ring grooves
• 1/8" NPT ports tapped into each runner for nitrous
• Suits a short length (compact) 14mm o-ring injector
• Will fit under most bonnets of Holden Commodores from VT-VF (170mm overall height).

Note: Clearancing will be required when using this intake with factory heads that have a raised shoulder along top above intake ports
