Description Fitment Guide Installation Instructions
The APR R1 Diverter Valve is a critical performance upgrade recommended at all stages of performance as it replaces the failure prone factory unit. The R1 is designed to withstand extreme boost pressures at the highest levels of performance, while offering lightning fast response thanks to the unit's friction-free diaphragm-based design. Unlike piston based units that can stick and bind in the winter, the APR R1 is virtually maintenance free, requiring no greasing or o-ring replacements, as is common with other units. Constructed from CNC-machined billet-aluminum with a high-temperature Nomex-reinforced diaphragm, the R1 is designed to be the last DV upgrade the engine will ever need!

Features:

  • Direct replacement
  • Billet construction
  • Premium friction-free diaphragm-based design
  • No sticking or binding like pistons
  • No maintenance like pistons
  • Nomex-reinforced diaphragm
  • Fits 1 inch inlet and outlet hoses

(Go Fast Bits) diverter valve plus install

Installed this GFB diverter valve to eliminate the OEM plastic one all together that are prone to failing. I also spent the little more instead of rebuilding the bottom of the OEM that GFB offers but doesn’t clear all cars. BOV option (any brand) can cause car to have lights & running rich issues if not tuned asap so this was the best option for me to pair with my neuspeed intake. Plug and play harness & works great ! Can tell has less slop from day to day traffic & daily driving.

Good Intake for the price !

This intake sounds amazing at low rpms ! Definitely using some more gas cause it’s hard to keep foot off the throttle lol. Was a tight fit on an 2014 Audi TT Quattro S Line. Engine cover does touch against the intake tubing but fits overall pretty well.

Some slight modifications to the car and the cold air heat shield was needed but otherwise it fit great. Can really hear her breath now!

Very nice!

Love my new side markers - very clean looking and unique in how they flash when turning left or right. The only suggestion I’d make is provide instructions for both installing them and for being very careful with the wire once you disconnect the old light housing Left side went in ok, but I lost the right side into the fender black hole which required me to remove the tire and unscrew most of the lining so I could find the wire!

A worthwhile upgrade

The kit arrived early and complete. All necessary parts were included and installation was straight forward. I installed this upgrade myself sitting on my garage floor.

All the turbo-y, sneeze-y sounds now! Little to no overboost at the high RPM range and boost comes on much more evenly now. Great piece of kit!
