The Integrated Engineering 1.8T longitudinal intake manifold was carefully designed to retain all of your factory components while delivering industry leading performance. Through extensive research and development, this intake manifold fits both 058 and 06A longitudinal engine bays. Unlike other manifolds on the market, the IE 1.8T longitudinal intake manifold does not require you to modify any portion of the cooling/fueling system, PCV sensors, or brake booster lines. Both large and small port options are available as well as throttle body size options.

Using the latest in Computational Fluid Dynamics (CFD) software, our engineers have optimized the manifold's airflow and power range for virtually any turbo charger. The largest power gains will be seen on setups using a GT28-30R/EFR 6255 or larger turbos, however due to the unique plenum and runner design even aggressive K04+ sized turbos will see gains throughout the RPM range. The pictured power graph is the final testing performed on a 2.0L stroker engine at 12 psi boost level. As you can see, this manifold shows excellent power gains through the mid-high range and very little low end power sacrifice with maximum gains of 80 HP on this set up.

Our plenum design has been generously sized and shaped to optimize and distribute airflow evenly to all 4 cylinders. A plenum design is only as good as the runners attached to it, so we carefully tune the intake manifold runner lengths and diameters. Dramatic power and torque increases come from making small changes to the runner design. CFD software is also used to research and develop an optimized velocity stack (bellmouth) design. Our engineers are equipped to research and test many designs. They found this manifold performs very well when used with a specific bellmouth shape that is flush with the plenum floor.

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 available with a machined throttle body flange to accept a 60mm (stock), 70mm (S4), or Hemi 80mm throttle body. Optional hardware allows you to retain 058 AEB drive by cable throttle body and the cruise control components. (larger than stock throttle bodies such as the 70mm & 80mm will require specialized tuning, contact your tuner for more info)
