Product Details


NEW UPDATED DESIGN! True 3.5″ intake for maximum airflow. Huge 6″ velocity stack air filter.

 CTS Turbo is proud to announce its TRUE 3.5″ velocity stack air intake system for the Audi 3.0T.

The OEM air scoop works in conjunction with their sealed airbox to seamlessly force cold air into our air intake system.  Air then flows through the high flow cone air filter, which utilizes an inverted cone design for maximum engine breathing. 

The single-piece CNC mandrel-bent aluminum intake pipe allows for smooth entry of cold air into the engine providing peak power gains ranging from 8-11HP.  All of the components included in the CTS air intake system work flawlessly together to provide increased horsepower and torque throughout the entire power band and an aggressive race-inspired sound.

Don’t waste money on intakes with silicon pipes – they collapse under vacuum and end up choking out the airflow! Keep your supercharger happy with our TRUE 3.5″ intake.


  • This intake is not CARB exempt and is not legal for street use in California & other states adopting CARB standards. Please check your local laws before purchasing.


Product Features

  • True 3.5″ mandrel-bent aluminum piping with black powder coating.
  • Massive 6″ velocity stack air filter with an inverted cone design that connects without reducers to the intake pipe.
  • 4 Ply silicon connector with stainless steel clamps.
  • Insulated air box with rubberized trim to keep the temperatures down.
  • Bracketry to prevent rattling under engine torquing.
  • Billet SAI breather adapter with billet bracket and SAI breather filter.
  • Gains are ranging from 8-11HP on a stock car.
  • Tuned vehicles are pretty much required to run this intake.

  • Not satisfied

    Installed on a 2012 s4. Supercharger whine volume was surprisingly low in comparison to older version. I would say 50% quieter. Not sure if this was intentional or a defective product. Overall not satisfied.

  • Buy With Confidence

    The only intake for the B8/B8.5 S4. I wanted to hear the supercharger whine but not the intake noise. Modded Euros recommended this unit and they were spot on. No intake howl, but now there is the distinctive whine this car should have had from the factory. Quality parts, great price and an easy 30 minute install. Can’t give it enough stars.

  • Great intake but 0/10 instructions

    Starting with the bad, I must say the instructions are very unclear, with the pictures being even less so. Each step is a simple sentence that doesn’t give much to work with. Quite simply, i’ve had more detailed instructions on the LED lights I installed on the interior than this intake.

    Otherwise, once you install this intake, its pretty solid and makes a wonderful noise when you step on the gas. Throttle responce seems to have improved a bit, and its quiet when you want it to be. Of the other intake options I would say this is one of the loudest.

  • CTS Turbo delivers AGAIN!

    A wonderful product ran all of their parts on my mk7 GTI and they never failed me. This intake is no different, if you want cooler temps and a noticeable difference in the way your car performs look no further. Plus you get that sweet loud supercharger whine that is so addicting.

  • Perfect Purchase

    I could not be a more happier customer. I am very pleased with the intake system I purchased. I love the sound my S4 makes when it whines up with this new intake. Great product and great company. Will be buying much more in the future. This is my one-stop-shop for my Audi S4.

  • 15' Audi S5- CTS Intake - DO IT !!

    This intake definitely EXCEEDED my expectations! The supercharger is now VERY audible and sounds amazing. Nothing but smiles while driving now, great sound inside and outside of the car. Looks great under the hood as well. I had this installed by a shop while a tune was being done so i cant comment on the install aspect.

  • Really brings out the super charger whine. Sounds good and very noticeable when you get on it, inside and outside the car.

  • Easy install. Amps up the supercharger whine which is cool.

  • Used it on my 2007 Audi A6 quattro little adjustments but worked great. Quality product.

  • Great product!

    Can't get over the sound! Everything about this intake is great. My only thing would be the lack a good video showing you how to install. The one provided spends most of the time with the guy covering what he's doing because he's standing right in front of the camera. Other than that, I love it!

  • can now hear my supercharger scream. great price and fast shipping
