The DOC Race Supra Intake Manifold was designed to replace your stock manifold and maximize airflow to your engine. It has been tested on William Taft's MKIV from Sydney Australia and made an easy 1092whp with a GT45R. Our manifold starts off with a CNC machined flange with integrated injector bungs. The runner length and diameter was determined through dyno testing of a variety of different manifolds. All runners have built-in CNC machined velocity stacks which we have been developed over the years and have been proven to increase airflow. The huge plenum will allow you to make power that is not capable with an OEM manifold. With this manifold, you can have streetable feel and still be capable of making 1500hp!! The throttle body flange is designed to accept the 5.0 Mustang 75mm up to 90mm throttle body. Manifolds can be ordered with provisions for the Idle Air Control Valve. This item comes fully polished unless noted before ordering.
You can also order this manifold with a fuel rail kit (Fuel rail add on listed below). The fuel rail kit comes with a -10an fuel rail setup for 14mm o-ring injectors as well as standoffs and hardware.
