performance longitudinal manifold

Important update 7/15/2014
We have received and approved the final intake manifold cast samples for final production, be sure to check out the first images of the completed cast manifold above. The intake manifold samples have passed quality control with flying colors and final production is underway. Shipment dates have been delayed with a new expected delivery date in September. Thank you for your patience, your car's performance will thank you. Pre-sale pricing has been extended for a limited time, be sure to reserve yours today and save 150.00 off!

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.

performance manifold

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.

dyno results

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.

made in usa

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)

FAQ:

What kind of power gains will I see?

Power increases are seen in mid-high rpm ranges, depending on turbo setup and displacement.

What else will I need to install?
We have included vacuum fittings and vacuum line to provide connections for all needed accessories. We also offer a full sized stealth vacuum manifold with more ports if needed for your setup.

Will I need tuning for this manifold?
For maximum performance, tuning is recommended. However, if the factory throttle body is used, it is not absolutely necessary. If upgrading to a larger throttle body, tuning is a must.

How does the IE intake manifold compare to others on the market?
Our intake manifold shows the best gains throughout the entire rpm range when compared to any of the competing manifolds. Vacuum ports have been placed on the underside of the intake manifold so there are no ugly vacuum ports visible on the top of the manifold. We believe this makes our manifold the most visually appealing piece on the market as well as the first manifold available as a direct fit with no modifications needed on both B5 and B6 chassis.

I see that the intake manifold is large-port only. Can I use this on my small port 1.8T head?
For all longitudinal small port heads, purchase IE intake manifold IEIMVA3.

Is it necessary to upgrade my fuel rail to install this manifold?
Our manifold was designed to work with the factory fuel rail, without modification required. We do offer a high-flow billet fuel rail for higher horsepower applications, which is also visually desirable.

I see that you offer the manifold in raw and black powdercoat finish. Is there a benefit to the black finish?
The black powdercoat finish is not only visually appealing, but it is much easier to keep clean. Raw cast aluminum parts easily collect dirt that is difficult to remove. The powdercoat finish does not show dirt easily and can be easily cleaned.

How do I know if my cylinder head is small port or large port?
The cylinder heads are stamped with the three-letter engine code on the front corner, near the #1 cylinder. Only the AEB longitudinal engine codes are the large port heads, all other codes are small port and require IEIMVA3 intake manifold to be purchased instead.
