Installation of COBB Tuning Upper Intercooler Pipe

  1. Install the BPV Pipe by sliding the 35mm silicone coupler and two 44mm hose clamps onto the end of the BPV.  Now slide the other 35mm silicone coupler and two more 44mm hose clamps onto the end of the pipe that comes off the lower intercooler pipe.  Loosely install the BPV pipe as shown but do not tighten any of the hose clamps.

  2. Install the upper intercooler pipe by first removing the two rubber grommets from the factory intercooler pipe.  Push out the metal sleeve and then the grommet.  Reinstall the rubber grommets and sleeves into the COBB intercooler pipe bracket.

  3. Slide the 45mm to 65mm silicone reducer along with a 2790 and 2793 T-bolt clamp onto the end of the turbo inlet.

  4. Install a 60mm to 65mm reducer along with the two remaining 2793 clamps onto the intercooler inlet.

  5. Slide the upper intercooler pipe into the silicone reducer on the turbo outlet first, and then onto the intercooler inlet.  Before tightening any of the clamps you will want to first reinstall the two 12mm bolts into the bracket on top of the radiator core support.

  6. Install the BPV return pipe support bracket usingthe flat washers and 5mm socket head cap screws.  Do not fully tighten them down yet.

  7. Temporarily install the air box and air intake duct.  By adjusting the orientation of the pipes you should be able to get the BPV pipe to sit in the cutout in the intake duct.  Some minor trimming may be required.

  8. You can now fully tighten all the clamps and reinstall the air box bracket, air box, plastic cover and undertray.  When you have verified that the BPV pipe is adjusted properly, tighten the cap screws on the bracket.

  9. Congratulations, you have successfully installed your COBB Tuning Evo X Upper Intercooler Pipe Kit.  Now go out and enjoy!
