COBB Tuning Volkswagen MK6 Boost Tap


Congratulations on your purchase of the COBB Tuning Volkswagen MK6 Boost Tap! The following instructions will assist you through your installation process. Please read them first BEFORE beginning the install and familiarize yourself with the steps and tools needed. If you feel that you cannot properly perform this installation, we HIGHLY recommend you take the vehicle to a qualified and experienced automotive technician.

Part List

  • Boost Tap
  • Retaining Clip
  • 1/16 NPT Barbed Fitting
  • 1/16 NPT Plug
  • 015 Buna O-ring 

Tools Needed

  • 5/16" Wrench

Installation of COBB Volkswagen MK6 Boost Tap

  1. Locate the crank vent hose connected to the intake manifold in your GTI. This is where the boost tap will install. 

  2. Remove the hose by squeezing the tabs on each side and pulling off of the intake manifold. 

  3. Before you install the boost tap, screw on the desired fittings to your boost tap. For our configuration we included one barbed fitting and plugged the other tapped hole. For this you can use any combination you want!

  4. Now take the COBB Boost Tap and place the female end over the barbed fitting the hose just came off of. Use the picture as a reference. 

  5. Take the retaining clip provided and clip the boost tap to the intake manifold. The clip slides over the grooves seen on the boost tap and will click into place. 

  6. To finish the install, clip the hose onto the boost tap. This should clip right onto the barbed fitting of the boost tap just like it did stock. 

Congratulations on your new COBB Boost Tap!
