034Motorsport High Flow Intake Manifold - Large Port | Transverse 1.8T

034Motorsport's Transverse 1.8T High Flow Intake Manifold was designed to be a direct bolt-in replacement for the stock intake manifold, and features a modular design, with a rotatable plenum that allows for driver side or passenger side throttle body locations. Featuring a 1.85L plenum, the 034Motorsport High Flow Intake Manifold was engineered not only for high-horsepower, big turbo builds, but also to offer noticeable improvements in low-end and midrange power, even on stock turbo configurations.
