Osir Design - Mask A4 B8 - Carbon Fiber - Audi A4 / A4 S-Line / S4 B8

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!

I have a 2014 Mk2 Audi TT and had this installed (still with the stock cat back) and it sounds & looks great ! This with the high flow cat gives it the no drone on the hwy and the note I needed with lite rumbles on low speeds and rpms as well. (Stage 2 tune is needed.) Pairing it with a cat back on other TT/TTS & MK5/MK6 builds will give different results of course on noise & drone. I’m happy with the price also with other options being well over thousands of dollars. I’ve had it a few hundred miles and so far so good !

Everything worked fine

Replaced my failing puddle lights with these. These were there best price I could find. They look great.

The products was great 👍

They where easy to install and I hope they will do the work.😊

They look great, give the car a quick update, are truly easy to install and operate perfectly.

Exactly what I needed

Great product! Fitment is A+

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 👌
