Congratulations on your purchase of the COBB Tuning Subaru Silicone Turbo Inlet! The following instructions will assist you through the installation process. Please read them BEFORE beginning the install to familiarize yourself with the steps and tools needed. If you feel you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.

NOTE: This methodology of installing a turbo inlet hose is more involved, as we remove the intake manifold. However, due to our turbo inlet hose being packaged with fuel system upgrades, removing the intake manifold streamlines the install of fuel injectors, and thus, we prefer this approach.

IMPORTANT! Installing this kit will require custom tuning or utilizing an appropriate Stage Power Package map if you have a matching mechanical configuration. Please consult with COBB or an authorized ProTuner in your area.


Parts List

Tools Needed



GR TMIC Removal

This removal applies to the following vehicles

  • 2008 - 2014 WRX
  • 2005 - 2009 Legacy GT
  • 2005 - 2009 Outback XT
  • 2008 - 2013 Forester XT
  1. Locate the factory BPV and remove the recirculation hose by squeezing down the hose clamp with your pliers.

        


  2. Remove the vacuum reference line from the rear port of the BPV




  3. Moving to the other side, unbolt the flange where it meets the turbo using a 12mm socket.

        


  4. Undo the hose clamp attaching the throttle body coupler to the intercooler.  This will typically require a phillips screwdriver, 7 or 8mm socket.




  5. Unbolt the remaining 12mm bolt going to the intercooler support bracket and remove the intercooler from the car.

            

While not strictly necessary, removing the intake manifold can make many things easier throughout the process as you can move many things out of your way all at once, and more easily see what is going on underneath as well.




Stock Inlet Hose Removal

  1. Park your car in a flat, level area and allow it to cool down.




  2. Remove the two clips holding the factory snorkel in place and remove it from the car.

       


  3. Using a 7mm, 8mm or phillips screwdriver (depending on your clamps) loosen the hose clamps on either end of the post MAF hose.

        


  4. You can then remove the post MAF hose from the car.


  5. Remove the front two hoses on the inlet.

        


  6. Unplug the electrical connections for the visible solenoid and the MAP sensor.




  7. Using a 6mm allen wrench or allen socket, Undo the bolt holding the inlet and solenoid bracket in place.

        


  8. Undo the 12mm bolt on the bottom right of the sensor/solenoid bracket.




  9. Mark the vacuum lines going to the solenoids and map sensor so you know which one goes where, then remove them from the fittings on each sensor.


  10. Unplug the rear solenoid electrical connector now that it's more easily accessible.




  11. Remove the bracket and sensors from the vehicle.

        


  12. Remove the 3rd from the front vacuum line now that it's exposed.




  13. Moving to the back, loosen up the hose clamp going from the inlet to the turbocharger.




  14. At this point you'll need to remove the squeeze-type clamp holding the BPV recirculation tube on to the turbo inlets large rear fitting.  It's fairly tight but some long pliers and a screwdriver to move the clamp to the correct orientation can help if you haven't removed the entire intake manifold.




  15. Unplug the rear crank breather sensor in the back and push the line forward to take it off.

        


  16. With that out of the way, pull the inlet forward slightly and upwards.  You should be able to slowly work it out without breaking anything off.
