High quality materials and design. For an early 00 B5 installation, kit requires you separately buy and install a 3/8 to 1/2 in. hose coupler at connection between PCV valve hose and F-Hose connection. Also cannot use factory N75 valve mounting bracket, and have to cut away a portion of this factory mounting bracket, to provide room for the new N75 valve location, when installed with an 034 Stage III kit with RS4 Airbox and RS4 Y Intake Pipe. It would be helpful to have installation instructions specific to this early B5 installation to clarify these needs. This kit was recently installed, and looks and runs great. Will update after putting some miles on the car!
This is much easier to work with than the brittle plastic parts. The kits worked great as-is for months, and I decided kept it when installing a custom catch can setup. Made everything much easier to route.
