Description
Dual Plenum 650 HV – high-volume intake manifold fabrication kit
The kit is suitable for intake manifold projects on 5- and 6-cylinder engines. Allow for the larger plenum chamber when planning the manifold fitment.
The two-chamber Dual Plenum design is intended to distribute charge air evenly between the cylinders. Air passes from the tapered tube through its flow slot into the plenum chamber, then through the runners to the engine intake ports.
The components are made from lightweight, strong, corrosion-resistant 6082 aluminium with good weldability. During fabrication, the tapered tube can be positioned to face forwards or backwards and to the right or left, to suit the engine bay and charge-pipe layout.
Included in the kit
- high-volume plenum chamber
- tapered tube and 180 mm extension
- flow-optimised end cap
- inlet cover plate
- flow-slot support bar for high boost pressures
- detailed fabrication and welding instructions
Engine-specific intake manifold flanges, runners, velocity stacks and a throttle-body flange are purchased separately. The MWS Motorsport range also includes aluminium heat shields for intake manifold projects.
