Description
The Integrated Engineering 1.8T transverse intake manifold is 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.
Carefully designed to increase midrange to high RPM power on your race or street-driven big turbo engine, large power gains will be seen on setups using a GT28-30R/EFR 6255 or larger turbos. The manifold plenum itself has been generously sized to ensure maximum cylinder charge and very carefully optimized to distribute airflow evenly to all 4 cylinders regardless of the loading conditions.
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. Your intake manifold is availble with a machined throttle body flange to accept a 60mm (stock), 70mm (S4), or Hemi 80mm throttle body. You do have the option to purchase the manifold with the 80mm flange, along with an adapter plate (sold separately) to allow the 70mm or 60mm throttle body to be ran now with plans of upgrading to the 80mm in the future.
This manifold has a feature set which is truly unique. The modular design allows for throttle body to be installed on either side, the first of its kind on this market. This will allow you to install the manifold, regardless of your charge pipe setup, with only minor piping modifications in most cases. Featuring aggressively sized 48mm inside diameter runners, the lower manifold section is tuned for medium to high RPM power. The carefully designed and flow tested velocity stacks deliver more air to the cylinder than any other manifold on the market.
