The Integrated Engineering intake manifold for transverse VW / Audi 1.8T engines has been engineered to provide market leading performance and features. Each aspect of this manifold was carefully tweaked and optimized by our engineers by using the latest in Computer Flow Dynamics (CFD) software. The design work was followed by an extensive round of testing on our in house Superflow engine dynamometer. The result of this extensive research and development is quite simply the most advanced, refined intake manifold the VW/Audi community has ever seen.

This manifold has a feature set which is truly unique. It is a modular design with a symmetrical plenum that allows placement of the throttle body on either driver or passenger side. The plenum itself has been very carefully optimized to distribute airflow evenly to all 4 cylinders regardless of the loading conditions. The plenum has been generously sized to ensure maximum cylinder charge at high RPM. Featuring an aggressively sized 48mm inside diameter, the lower manifold section is tuned for medium to high RPM power. Carefully designed and flow tested velocity stacks deliver more air to the cylinder than any other manifold on the market.

Impeccable execution ensures that this manifold can actually deliver. Each manifold is cast, machined, inspected and packed all in the USA by a major OE supplier. The manifolds are cast from a special self aging, self hardening alloy with especially strict requirements for chemical composition. Top of the line Japanese machining centers machine all major surfaces of the parts in one setup, ensuring perfect fit, finish, and maximum value.

The intake manifolds now come with the throttle body flange of your choice machined onto the plenum. The billet throttle body adapters are no longer needed to run a 70mm or 60mm on the manifold. You do have the option to purchase the manifold with the 80mm flange, along with the adapter plate to allow the 70mm or 60mm throttle body to be ran now with plans of upgrading to the 80mm in the future.
