3.0L Plenum

It is constructed from A356-T6 heat-treated aluminum, providing extreme durability, and features a three-liter plenum for sufficient volume for both stock and built engines. This manifold is designed with a forward-facing throttle body location, optimized for RWD vehicles. It offers comparable top-end power to other manifolds while increasing mid-range torque. The 74mm inlet accepts a B series throttle body or a DBW throttle body with an adapter. It also includes a K series MAP sensor port for simplified wiring and tuning, and a K series idle air control valve (IACV) port positioned for easy connection to OEM engine harnesses. The design ensures improved fitment in RWD engine bays, offering clearance for the stock K series belt tensioner and idler pulley, and a higher plenum for easier access to bolts and wiring. It is available with or without the TSX (RBB) style water port to fit all K20 and K24 heads without extra fittings, and includes a built-in throttle cable bracket mount. Optional gaskets, hardware, and fittings are also available.
