Technical Information:
Intake manifold:
Bring your 2.5L 5 cylinder VW engine to life with the Integrated Engineering cast intake manifold. The factory 2.5L 5 cylinder intake manifold is designed to channel air into the engine sufficiently well to meet the original horsepower targets, while being cost effective and easy to install. This compromise means that there is room for significant improvement. The IE performance manifold has been designed from the bottom up to put performance first. IE engineers exploit careful tuning of the intake manifold runner lengths and diameters to create a resonance effect which rams more air into the cylinders. The plenum and runner designs have been carefully optimized with computer software for maximum flow, allowing your engine to breathe easier and perform at its best.
Integrated Engineering 2.5L Stage 2 Intake Manifold Software:
The IE Stage 2 performance flash for VW 2.5L engines is designed specifically to re-calibrate the naturally aspirated 2.5L engine for use with the IE intake manifold. This software incorporates the same attention to detail as the performance intake manifold and enables IE to offer a complete performance package. With use of our in-house Dynapack DP42 dynamometer, we are able to do repeated runs to test each change that is made to the software and confirm performance and drivability.
Although ECU re-calibration is used to increase the power output from the engine, we also focus on increasing the all-around drivability. That is to not only provide more horsepower and torque, but make the driving experience more enjoyable by removing rev hang, increasing throttle response, and increasing the rev limiter. With this software, IE intake manifold, and an IE cold air intake kit, power output is increased to 180FT/LBS and 218HP. With such a significant power increase, it makes the vehicle much more enjoyable to drive, with plenty of power available until redline.
IE Cold Air Intake Kit:
The included IE 2.5L manifold air intake kit is designed to make the installation of your new Integrated Engineering 2.5L 5 cylinder intake manifold simple with our direct-fit intake kit. This kit will connect your throttle body to your mass airflow sensor, and place the air filter right behind the driver's side headlight in a partitioned area that only sees fresh airflow. Our specially-made high flow intake pipe features provisions for the valve cover breather, block breather, and SAI pump, so nothing is left unplumbed.

Increased Plenum Volume:
This plenum on this manifold has been generously sized and shaped to distribute airflow as evenly as possible to all 5 cylinders. The increased internal volume is a massive improvement over the factory piece and ensures a steady supply of air for the engine.
Flow Tuned Runner Design:
By using a cast aluminum construction manifold, our engineers are able to properly size and shape the manifold runners and velocity stacks for optimal performance. This runner flow and resonance tuning is a huge contributor to the over-all performance of the intake manifold, and is not possible to achieve on hand welded manifolds generally available for this platform. Featuring aggressively sized runners that have been optimally tuned for large power increases throughout the mid-high RPM band. Our engineers employ CFD software to research and develop an optimized runner and bellmouth design, after many revisions to the design they have achieved the best runner shape, size, and velocity stack for the 2.5L application.
Removed Speed Limiter and Increased Rev Limit:
The factory ECU speed limiter has been removed to make sure the increased power and torque can be used to its full potential on straightaways and drag strips. The ECU has also been calibrated to extend the rev limiter to match the powerband of the IE intake manifold. This specific flash has raised the rev limiter increased to a 7200RPM, which is a perfect match for the new performance manifold powerband and the OEM engine internals.
Engineering Process:
Unlike other manifolds on the market that are simply welded and made to fit on the car, IE's performance intake manifolds receive special treatment from start to finish. IE's engineering department looks at each specific application and designs an intake manifold with a properly sized runner and plenum. Then IE begins a series of prototyping and testing countless revisions to the design to ensure optimum performance.
Integrated Engineering's engineers use Computational Fluid Dynamics (CFD) software to optimize the runner and velocity stack (bellmouth) system for proper resonance tuning and airflow. Unlike competitor manifolds, they use this process on each manifold to design the application-specific runner system to maximize airflow delivery to the cylinders.
Once the manifold has been designed and flow has been optimized, the 3D models head over to IE's 3D printing studio to manufacture the initial prototype. The 3D printed manifold is fastened onto their in-house engine dynamometer and in-house chassis dynamometer for testing. To validate the plenum, runner, and bellmouth design, they test each revision in a controlled environment. Once all testing data has been collected, it is analyzed and used to determine if changes are necessary before going to production.

Fitment Restrictions
Power Steering
This manifold will fit all VW 2.5L engines with the electric power steering system. Some later style engines use a hydraulic power steering pump, which sits right below the factory intake manifold. If your car is equipped with a hydraulic power steering pump, this manifold will not fit.
Automatic Transmission Tune Required
Automatic vehicles require a matching IE TCU Transmission tune to allow high revving of the automatic transmission. The stock automatic tune has internal transmission rev limit controllers that shift before the manifold and software can make the extra power gained through the upgrade. IE's Auto Transmission Tune removes this limiter allowing full advantage of the manifold & tune.
