(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.

The side markers were very nice upgrade’s. I love them 😍

Forge intake pipe

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!

Black MK1 Audi TT Grill / Rings

Looks much better than the factory stock grill. Perfect fit. Purchased two sets just to have a spare in case something happens to the first one.

Impressed, perfect fit install took 5 minutes and turbo lag is way less and the sound with forge devertor valve is awesome 👌

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.

Michael McLoughlin

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!

Thank you for sending the TT carbon fiber eyelids, they were well wrapped and damage free. I look forward to placing them on the headlights.
