Integrated Engineering 1.8T Transverse Intake Manifold Install

In this DIY, we will be covering the  installation of the Integrated Engineering intake manifold for transverse 1.8T engines. This kit needs to be installed by a professional or by an experienced technician. Integrated Engineering is not responsible for any damage caused by incorrect installation. Serious engine damage can occur from incorrect installation. 

Kit contents: (1) Intake manifold runner section (1) Intake manifold plenum section (1) Gasket for between the manifold sections (6) Stainless steel socket head cap screws, 1/4"-28, 2.5" length (2) Stainless steel socket head cap screws, 1/4"-28, 1.5" length (2) Stainless steel socket head cap screws, 1/4"-28, 7/8" (Holding manifold section together in the box) (1) Stainless steel socket head cap screw M6x1.0, 16MM length (1) Stainless steel flat washer M6 screw size 12MM OD (1) Intake manifold to head gasket (1) Assembly diagram

Before beginning the installation, unpack and inventory all components on a flat surface and verify that all pieces necessary are there before proceeding.

1. With your car on a level surface, begin disconnecting your fuel rail. Disconnect the injectors (label the connectors per cylinder), fuel feed and return lines, FPR vacuum line, and remove the two mounting bolts for the rail. Remove the fuel rail and injectors, be sure to place them on a clean surface. 

2. Disconnect the throttle body from the harness and loosen the clamp on the coupler and pull it away from the throttle body. Loosen and remove the eight bolts and two nuts from the manifold flange. Disconnect all vacuum lines and label them. Unplug and remove the IAT (intake air temp) sensor and set it aside. Lift the intake manifold up and off of the head. Remove the throttle body from the manifold and set it aside.

3. Install the provided gasket onto the runner section of the manifold. Orientate the plenum onto the runners with the throttle opening facing the side for your specific setup. Install the two 1/4"-28, 7/8" long bolts through the runners into the plenum and torque them to 8 ft/lbs.

4. Install the remaining 1/4"-28 bolts into their respective holes and torque to 8 ft/lbs. NOTE: leave the two center bolts on the bottom side of the plenum out for securing the vacuum manifold to the intake manifold at a later point.

Steps 5-10 are used if you are installing the Integrated Engineering vacuum manifold kit.  Vacuum manifold kit is available separately here.

5. Install the provided 3/8" NPT to -6AN adapter fitting into the port on the end of the manifold using Teflon tape or thread sealant.

6. Install the barbs and plugs required for your specific setup in the vacuum manifold.  Install the 3/8" NPT to -6AN adapter into the end of the vacuum manifold using Teflon tape or thread sealant.

7. Using the provided socket head cap screws and washers, loosely install the L-brackets onto the vacuum manifold in the orientation that best suits your application. Temporarily install the vacuum manifold onto the bottom side of the intake manifold with the remaining 1/4"-28, 2.5" length bolt. Tighten the bolts holding the L-brackets to the vacuum manifold. Remove the vacuum manifold.

8. Loosely Install the provided braided line onto the vacuum manifold, it will be tightened at a later point in the install. Route your vacuum lines from your accessories (BOV, FPR, brake booster, etc.) to the vacuum manifold leaving plenty of slack for adjustments. You can always trim the excess when the manifold is fully installed.

Additional vacuum line is available here.

9. Slide the included one time use single ear clamp onto the brake booster line, it will be tight but it will fit. Be sure to leave enough slack in the vacuum lines so they do not kink when you permanently bolt the vacuum manifold on. Using a special set of ear clamp pliers or a set of cutter pliers, pinch the ear on the clamp closed on the break booster line.

10. Secure the rest of the vacuum lines at this time with the included wire ties.

Steps 11-13 are used when installing a throttle body adapter. If you are using an 80MM Hemi throttle Body, skip to step 14. 80mm Hemi throttle body is available separately here. 

11. If you ordered the intake manifold for a 60mm(stock) or 70MM(S4) throttle body, you will have received a CNC billet throttle body adapter kit. Be sure your kit has the pictured hardware before you proceed. The adapter plate has a 1/8" NPT port on one side. This can be utilized for a water/meth injection nozzle, or any other accessory that requires this type of port. Or you can plug the port with the supplied plug.

12. Install the throttle body adapter plate with the supplied gaskets and bolts onto the intake manifold. Torque the bolts to 7 ft/lbs

13. Install your throttle body onto the manifold spacer with the correct gasket, bolts, and washers. Torque the bolts to 7 ft/lbs.

14. If you are using a 80mm Hemi throttle body, install it to the manifold along with the manifold IAT sensor.  Install your Integrated Engineering cobra head coupler onto your charge piping leaving the clamps loose.

NOTE: A cobra head may only be needed when installing the manifold with the throttle body on the passenger side.  Cobra heads are available separately in many sizes here.

15. Place the intake manifold gasket on the head. Slide the Integrated Engineering intake manifold down onto the studs on the head, sliding the cobra head coupler onto the throttle body. Install manifold hardware into head and torque to factory specs. 

Note: If you do not have a large port AEB head, a Integrated Engineering transition spacer is need for small port heads.  Available separately here.

16. Using the remaining two 1/4"-28, 2.5" length bolts, install the vacuum manifold onto the underside of the manifold. Torque the bolts to 8 ft/lbs. Thread the braided line onto the intake manifold fitting and tighten both ends of the line.

17. Connect the IAT sensor. Tighten the cobra head coupler onto the throttle body and charge piping.

18. Install the fuel injectors into the bosses on the manifold. Reconnect the injector harness clips to their corresponding injector. Carefully press the fuel rail onto the injectors, install the factory injector locking tabs, and bolt the rail to the manifold with the required hardware.

Integrated Engineering 1.8T Billet Fuel Rail pictured, available separately here.

19. Reconnect your fuel lines to the fuel rail.  If you are using an aftermarket fuel rail (sold separately), install the FPR with an adapter or fuel line to an aftermarket AFPR and return fuel line. Secure the vacuum line to the FPR.

20. Double check that all fittings and bolts have been correctly tightened before starting the engine.

    • Sorry, as of right now we only carry engine specific parts for Audi, VW, BMW, Porsche, Euro, etc... We do have many universal parts such as fueling options, turbo DIY, fittings, etc... but no intake manifolds.

  • hello can i use the manifold with my stock fuel ray???

    i buy one but keep my stock fuel ray

  • If i do have the IE fuel rail and the IE FPR housing. What adapter size do i need to connect them?

    Also you guys should put together a kit that includes everything needed for this instead of having all the items separate.

    • Tyler,
      You would need a -8AN o ring to -6AN o ring: http://www.intengineering.com/6an-to-10an-o-ring-boss-male-fitting-black
      We are working on install kits, but I do not have an ETA yet.
      Thank you.

      • The link is broken. I saw that you guys have the reducers but one end doesn't have the O ring. Can that be used?

          Hi Tuan,

          I think you are referring to our throttle body adapters. They do not use an o-ring but we supply a gasket for both sides of the adapter plate. You can check out all the TB adapters we offer here: http://www.performancebyie.com/search/?q=throttle+adapter&order=relevance&dir=desc
