Stock BPV Removal

  1. Remove the three 10mm bolts holding the PCV crossover tube in place.

  2. Pull it out of the hose on one end then turn it over to the other side and out of the way (Or remove entirely).



  3. Remove the spring clamp (or zip tie in our case) holding the stock manifold reference line in place.



  4. Using a pair of pliers, remove the return line from the bypass valve. Each application is a bit different.



  5. Using a 10mm or 12mm socket with ratchet or 10mm or 12mm open end wrench (depending on application), remove the 2 bolts that hold the bypass valve in place.

TIP: Make sure to keep an eye on the factory gasket behind the BPV.  They can fall when you remove the valve and end up in difficult to reach locations!




COBB BPV Installation

  1. Insert the BPV into the recirculation hose.  Sometimes it can help to have a screwdriver or other object to hold the hose in place from underneath.

        

  2. Slip the gasket (if your model requires one) in between the BPV and the intercooler then begin hand tightening the two 12mm bolts on the flange.

  3. Install the manifold reference line to the top barbed fittings.



  4. Install a hose-clamp or zip tie to hold it in place properly.



  5. Reinstall the PCV crossover tube with the three 10mm bolts.



  6. You're all done!  Go out and enjoy.

Please place the included CARB EO Sticker in a Clean, Visible Location.
