New from Enforcer, the CNC Machined Intake Manifold. Comes with 2 CNC Teflon gaskets that insolate heat between the manifold  and carburetor. The manifold is machined to accept a standard big bore cabruretor with .501 bores such as WT257, WT644, WT813, and Warehouse Hobbies CA5003. The port side of manifold is matched to the stock G321 and G260 Zenoah engines and can be easily port matched if required using a moto-tool. This intake manifold is not equipped with a pulse tap fitting and is designed to be used on a clutch-less engine.
