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.



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.



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.


The Integrated Engineering 2.5L ultimate power kit 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 is easily plumbed to your mass air flow sensor using the included 2.5L manifold air intake kit.


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 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.


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.


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.

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.


Although the manifold will fit, automatic vehicles are equipped with internal transmission rev limit controllers that shift before the manifold and software can make the extra power gained through the upgrade. For this reason, IE intake manifold is not recommended for automatic vehicles.


  • Will this manifold fit my car?

This manifold will fit all VW 2.5L engines from 2005-2013 with the electric power steering system. Some later style engines use a hydraulic power steering pump, which sits right below the factory intake manifold. We recommend installing these on manual transmission cars only, as the gains are in the higher RPM range, which cannot be reached on automatic ECUs (transmission controller has internal rev limiter). ECU flash is available for 2005-20014 ECUs.

  • Can I install this manifold on an automatic transmission car?

The intake manifold will physically fit on automatic cars, but the power gains will not be  seen as they would with manual transmission cars. The power gains are seen in the high RPM range, which is not reachable on automatic cars, as they have rev limiters in the transmission controllers that cannot be removed.

  • Will my factory fuel rail work?

Although we recommend using our billet fuel rail which compliments the beautiful cast manifold nicely, your factory fuel rail will also bolt up to our intake manifold using the included hardware.

  • What throttle body can I use with the IE cast intake manifold?

Our intake manifold is designed for use with the factory throttle body, which is a direct fit. We include the necessary hardware and seal for the throttle body with each intake manifold.

  • What kind of gains can I expect from the IE intake manifold on my stock 2.5L engine?

Along with our software and intake kit, we have shown gains of 48.2bhp over the stock power levels on manual transmission cars revving to 7200rpm.

  • Can I use this manifold with my turbo setup, or will it only work for naturally aspirated applications?

Yes! We have designed our manifold to offer great gains on any setup, whether naturally aspirated or turbo.

  • Will this manifold be a direct replacement for my factory intake manifold?

Yes! With our plenum being larger than the factory plenum, the throttle body location is slightly different. It will require use of our IEIMVB2 intake kit, making the manifold install simple.

Fantastic customer service and great performance gains
I would like to thank I.E.s' tuner Damon Earl for the time he spent helping to get my car flashed he spent hours on getting the tune to work with my 07 rabbit on a Saturday when they were not normal hours I'd like to thank him for his fantastic service and spending the time to make things work . I'm very happy with the performance gains in the fuel economy gains that I got from this set up. Absolutely fantastic.

Best manifold ever!
I’ve had Integrated Engineering’s 2.5 Power Kit installed for about a month now and I have been amazed by it in every way. It’s not just more power; it’s where the power is made. It is much more usable, meaning the torque is more linear and doesn’t come in bulk lower in the revs. Now there is actual power past 5k which there was basically none before. Also the growl the exhaust produces makes it sound exotic. Most of my friends are Honda guys, but they are in love with the way this car sounds. On top of a power increase and the sound, I’ve noticed a big bump in mpg. I estimate I’m getting between 32-35 mpg when I’m not getting on it which is awesome for any car, let alone a 2.5 liter. Even when I am getting on it the gas mileage is better. Overall I am extremely happy with the power kit and will continue to buy and recommend Integrated Engineering’s products to everyone I know!
