Made from Ergal 7975-T6 and black anodized, the MHR butterfly housing with a diameter of 37mm was specifically designed to achieve maximum performance in combination with the Double PowerCam, providing the right intake to the engine in this setup.

This housing works perfectly with the oversized intake trumpets specially designed by Marco Magistrati.

The internal diameter of the butterfly housing expands up to 37 mm, while its length remains identical to the original to allow easy installation in its standard position between the cylinder head and the airbox.

Its internal ducts are cylindrical adjoining the trumpets, gradually becoming oval at the connectors. Thanks to this shape variation inside, fresh gases are pushed more energetically into the cylinder head, which, having two intake valves, requires a considerable width, provided by the oval section that continues to the end of the manifold.

The specific trumpets for the MHR butterfly housing are calculated and optimized to achieve maximum performance from the oval sections of the bodies, exploiting the perfect harmonization of the entire duct.
