F411 - 4 barrel intake manifold 13B Cosmo-Semi PP
This manifold is designed to suit a 13B Cosmo large port engine with Semi PP porting.
The Xtreme Rotaries 4 Barrel Intake Manifold has been manufactured from lightweight aluminium and specially heat treated for added durability and strength. All the intake runners have been specially tuned so that they are the same length to suit high HP fuel injection engines (many of our competitors' manifolds are suited for a Holley carburetor and have a short front runner and longer rear which make them inferior for fuel injection set-ups).
The manifold was designed to be as compact as possible without sacrificing flow. This allows easier fitment into small compact engine bays and RHD vehicles. It also has the centre bolt above the intake port and the material to fit another one below the port if needed, which is a must for high boosted engines or the gasket will leak or fail on the primary port. All port positions, bolt holes and profiles are fully CNC machined to ensure vital accuracy and a quality fitment that Xtreme Rotaries has become known for.
This manifold can also be used with FD/S6-8 engines, but the plates must be machined to a Cosmo intake runner. Xtreme Rotaries perform this machine work, click here for more information.
