We have carefully engineered and tested this intake manifold in house to get the best results possible in any condition. Due to the unique plenum and runner design, your 2.5L 5 cylinder engine will be allowed to breathe the way that it naturally wants to, this piece will allow for great gains over the factory intake manifold, extending the powerband further into the RPM range. We have carefully engineered and tested this intake manifold in house to get the best results possible in any condition. During testing performed on our in house engine dyno, the IE 2.5L intake manifold produced excellent power gains through the mid-high range and very little low end power sacrifice with maximum gains of 48.2BHP over the factory manifold.

Note
-This manifold has been designed to provide large power gains for naturally aspirated, as well as turbo applications.

IE 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 Integrated Engineering 2.5L performance intake manifold has been carefully designed to fit 07K engines while retaining all of your factory components. Through extensive research and development, this intake manifold fits with no modifications to the engine bay, vacuum system, emissions systems, fuel system, or coolant system. With the plenum being larger than factory, the throttle body placement is moved a small amount, which can easily be plumbed to your mass air flow sensor using our 2.5L manifold air intake kit (part number IEIMVB2, sold separately).

Notes
-This manifold is a direct fit for all VW 2.5L 07K engines from 2005-2012 with the electric power steering system. Many later style engines (2012+) use a hydraulic power steering pump, which sits right below the factory intake manifold and will not allow this manifold to be installed. Please verify if your vehicle utilizes a electric or hydraulic power steering system before ordering.

-Although this manifold will physically fit on automatic transmission equipped vehicles, the power gains are seen in the high RPM range, which is not reachable on automatic TCU (transmission control unit).

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.

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 acheive 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 acheived the best runner shape, size, and velocity stack for the 2.5L application.

To compliment the impressive performance of the manifold design, IE engineers have taken special care to make a visually appealing piece that not only compliments, but enhances the look of the 2.5L engine bay. The beautiful USA cast aluminum surface is available in raw or powdercoated satin black finish, the easy to clean powdercoat will ensure the manifold stays looking nice for a lifetime. The top of the manifold features a brushed metal recessed IE logo plate.

Note
-The black powdercoat satin finish is available as an add-on option for an additional 75.00

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. Our engineering department looks at each specific application and designs an intake manifold with a properly sized runner and plenum. Then we begin a series of prototyping and testing countless revisions to the design to ensure optimum performance. Our 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, we 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 our 3D printing studio to manufacture the initial prototype. The 3D printed manifold is fastened onto our in-house engine dynamometer and in-house chassis dynamometer for testing. To validate the plenum, runner, and bellmouth design, we 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.
