Does This Fit Your Car?



Bring 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.

Installation 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.


Optimized bellmouth inlets create maximum power throughout the RPM range
Thick wall cast construction for durability in N/A and turbo applications
100% engineered, tested, and cast in U.S.A.

Included with manifold:
Head flange hardware
Head flange seals
Throttle body screws
Throttle body seal
Fuel rail screws




Will this manifold fit my car?
---This manifold will fit all VW 2.5L engines from 2005-2012 with the electric power steering system. The later style engines (2012+) 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).

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 48.2hp 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.

I already have an aftermarket intake on my car, can I use it with this intake manifold?
---To accomodate our larger plenum, the throttle body was slightly moved, so most standard intake kits will not be a direct fit without modification. We offer an intake setup specifically for use with our manifold, part # IEIMVB2 (sold separately).


"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!" - Josh T.
