Product Info

inline five cylinder intake manifold

Take your 2.5L 5 cylinder engine to the next level with the performance leading Integrated Engineering 2.5L 5 cylinder Basic Power Kit! This 2.5L manifold kit includes the IE 2.5L 5 cylinder intake manifold and matching IE 2.5L stage 2 software.

reliable performanceBring your 2.5L 5 cylinder VW engine to life with the Integrated Engineering cast intake manifold. By allowing your engine 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. This unit is designed and manufactured completely in the United states, utilizing a special self aging, self hardening alloy with especially strict requirements for chemical composition.

manifold power kitInstallation is made simple, as they are a direct replacement for the plastic intake manifold. 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 intake kit, sold separately. We have designed this manifold to provide large power gains for naturally aspirated, as well as turbo applications.

ie stage 2

Integrated Engineering stage 2 manifold ECU software
An ECU re-flash is required to get the most performance out of the IE 2.5L 5 cylinder intake manifold. This software was developed over extensive dyno time and many revisions to the file to gain every ounce of power when using the Integrated Engineering intake manifold. The ECU flash offered will only work with manual VW 2.5L models. We currently do not have support for automatic ECUs, as they are limited by the transmission controller rev limiter.

2005-2014 ECUs must be mailed to Integrated Engineering upon purchase. ECU will be returned with flash along with the rest of your order.

Tuned specifically for the IE 2.5L intake manifold
Rev limit raised to 7200RPM
Speed limiter removed
Increased horsepower and torque
Improved engine response
Available for 2005-2014 ECUs



IE offers three options to deliver the software to your car. Read below to explore each option and choose the best that meets your needs.

powerlinkIE PowerLink
The Integrated Engineering PowerLink handheld OBD programmer is a powerful device capable of reprogramming your ECU with performance files. It can store multiple files, allowing a complete recalibration of the ECU for different octane settings or boost levels. It can also put the ecu completely back to stock, not stock load levels. Finally, it can also read and clear OBD trouble codes. All of this is accomplished on device with a full color touchscreen interface. Files can be downloaded for tuning and uploaded back to the device with the included USB cable, and any Windows XP/7/8 PC. No external power is ever required.


Adding this device allows total control over your ECUs engine calibration. You will be able to quickly (5-10 minutes) switch between calibrations. These are not partial calibrations changing just a few settings, but rather complete calibrations for each octane / boost. It also allows further collaboration with the tuner, as files can be exchanged via the internet, rather then relying on a 3rd party installation shop. (IE PowerLink is an additional 259.99) Not available for 2009 - 2014 ECUs


IE direct port loaner tool
At Integrated Engineering, we want to make it as easy and convenient for you to flash your ECU with our performance software as possible. For that reason, we have a loaner tool program. Under this program, a case containing a flash tool, laptop, charger, and instructions is rented to you. All you need to complete your flash in your driveway is an internet connection (wifi or ethernet), our loaner tool kit, and a 10 amp charger. The process takes about half an hour to read, and then within 24 hours (during the week) you will be provided a tuned file which takes about 20 minutes to write to the ecu. Not available for 2009 - 2014 ECUs

Loaner tool process overview:

  • -Call customer service to place your order
  • -A loaner kit will be shipped to you at the shipping speed of your choice
  • -Set aside 1 hour of time to read the ECU and upload the stock file
  • -Within 24 hours you will receive a tuned file (during the business week)
  • -Take about 45 minutes of your time to recalibrate your ecu with the tuned file
  • -When we receive the kit in good condition your deposit will be refunded (you are responsible for ensuring proper packaging and shipping for the return trip)

Loaner Tool Rules:

  • -USA or Canada only
  • -The rental period is 3 business days from when you receive / sign for the package (Each day after this period will be billed an additional $75 out of your deposit)
  • -You are responsible for correctly packaging the kit for return shipping to us
  • -Use the kit responsibly, keep it clean and dry, and please do not beat up our parts
  • -Integrated Engineering is not responsible for ECUs damaged by errors in the recalibration process caused by not following the directions

Loaner tool instruction manual can be seen here.


Mail-in service
When choosing our mail-in service to upgrade the software, we require your ECU to be sent in for bench flashing. This process will be completed in less than 24 hours and then shipped back out to you. Please contact us if you have any questions or concerns concerning the flashing procedure for your specific vehicle.

Mail-in service process overview:

  • -Call customer service to place your order
  • -Package your ECU carefully and use the shipping speed of your choice (IE is not responsible for damgaed ECUs during shipping)
  • -Once received, the ECU will be bench flashed within 24 hours and returned via customers shipping speed of choice


Will this manifold fit my car?
---This manifold will fit all VW .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.


"Ive had Integrated Engineerings 2.5 Power Kit installed for about a month now and I have been amazed by it in every way. Its not just more power; its where the power is made. It is much more usable, meaning the torque is more linear and doesnt 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, Ive noticed a big bump in mpg. I estimate Im getting between 32-35 mpg when Im 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 Engineerings products to everyone I know!" - Josh T.
