CTS Turbo - Resonator Delete Kit – B9 Audi S4 3.0T

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.

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 😍

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!

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!

Fits like a glove and the quality is top notch. This will look great with all the other carbon bits on the car. To be honest the fit is so good, you can probably get away with using a industrial adhesion backed Velcro. IMO.

Beyond expectations!

Perfect addition to a beautiful car

It's really cool, great turbo sounds, great price, only gripe is instructions could be more detailed with a video

Great quality and look awesome very happy with purchase

TT mats... Great original look and texture , Happy with everything !!!! William

I bought these to replace another set of lug bolts I had recently bought. The original set had kind of sharp and badly cut threads which would become overly tight in my wheel hub even when torque’d to spec. These Nuespeed wheel lugs were machined well and have been much nicer to take on and off. A little more expensive but, worth it to not worry about snapping a lug when removing the bolts anymore.

Paired this with a malian downpipe on my 225 roadster and it has a fantastic sound. Lots of turbo noise too.

Was a little late, but everything was perfect!!!

I was considering just upgrading the brakes altogether, but I decided to try red stuff brake pads first. They are exactly what I needed.
