Remove the Top Mount Intercooler
Using a 12mm socket with ratchet, remove the 2 bolts that hold the bypass valve in place and remove it from the car.
This removal applies to the following vehicles
- 2008 - 2014 WRX
- 2005 - 2009 Legacy GT
- 2005 - 2009 Outback XT
- 2008 - 2013 Forester XT
- Locate the factory BPV and remove the recirculation hose by squeezing down the hose clamp with your pliers.
- Remove the vacuum reference line from the rear port of the BPV
- Moving to the other side, unbolt the flange where it meets the turbo using a 12mm socket.
- Undo the hose clamp attaching the throttle body coupler to the intercooler. This will typically require a phillips screwdriver, 7 or 8mm socket.
- Unbolt the remaining 12mm bolt going to the intercooler support bracket and remove the intercooler from the car.
Remove Factory Heatshield
It may be worth spraying down the bolts with a penetrating oil and allowing them to sit for a little while in order to allow them to come lose more easily without any breakage.
- Using your 10mm socket remove the two bolts from the driver's side of the heat shield.
- Followed down by the one on the rear passenger's side.
- And the two low down near to the passenger's side frame rail.
With those items removed you can now remove the heatshield from the car.
It may require re-clocking the transmission dipstick in order to have the clearance needed to remove the heatshield easily.
- Now is a good time to check out the heat shield bracket as the factory units are quite prone to cracking and damage. Replace yours as needed.
Turbo Heat Shield Installation
- Hand install one of the supplied 10mm bolts along with a washer into the lower up-pipe/turbo support bracket.
- Slide the heat shield into place with the cutout over the loosened bolt on the lower mount.
- Loosely install the other two bolts on the top and inside of the heat shield.
- Slide the heat shield around a little bit to make sure the wastegate arm isn't hitting the bracket and then tighten down each bolt with a 10mm socket.
- Reinstall the intercooler in the reverse order of removal.
- Go out and enjoy!
