Integrated Engineering 2.5L 5 Cylinder Intake Manifold

Integrated Engineering

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.

Integrated Engineering has designed this manifold to provide 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 2005-2016 with the electric power steering system. Mk6 Jetta sedan and B7 Passat models use a hydraulic power steering pump, which sits right below the factory intake manifold. 

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 show gains of XXhp over the stock power levels.

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.
