New design from Enforcer, the CNC Machined Intake Manifold. Comes with 2 CNC Teflon gaskets that insulates heat between the manifold  and carburetor which can cause vapor-locking. The manifold is machined to accept a standard big bore carburetor with .501 bores such as WT257, WT644, WT813, and Warehouse Hobbies CA5003. The port side of manifold is matched to the stock XForce 23cc air-cooled, XForce XF-26M, and G260 Zenoah engines and can be easily port matched if required using a moto-tool. This intake manifold is equipped with a pulse tap fitting and is designed to be used on engines with a clutch.
