DESCRIPTION

CTS Turbo is proud to announce our new intake system for the B9 AUDI A4, AllRoad, A5, S4, S5, RS4, RS5 (2017-2019 models)

We designed our system to work in conjunction with the OEM air scoop to seamlessly force cold air into the air intake system. Air then flows through our high flow 6″ velocity stack air filter for maximum engine performance.

Our single-piece proprietary molded silicone couplers allows for smooth entry of air into the engine providing peak power gains ranging from 10-12HP on a stock car.
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. Turbo spool up and diverter valve release are a lot louder!

Features:

  • Massive 6″ velocity stack filter, largest on the market
  • 3.5″ silicone turbo inlet hoses for both 4-cylinder and 6-cylinder engines (5-ply construction, will not collapse)
  • Heatshield to keep air temperatures as low as possible
  • Easy install and perfect fitment
  • Increased engine performance, less turbo lag
  • Sporty sound under acceleration and loud pressure release
  • Gains of 10-12HP on stock vehicles, tuned cars will gain even more!
  • The kit comes with parts to install on 1.8T, 2.0T, 2.9T and 3.0T engines (fits MAF-LESS cars)

Fitment:

  • B9 A4 (2017 – current)
  • B9 AllRoad (2017 – current)
  • B9 S4 (2018 – current)
  • B9 A5 (2018 – current)
  • B9 S5 (2018 – current)
  • B9 RS4 (2018 – current)
  • B9 RS5 (2018 – current)

Does not fit cars with a MAF sensor.

Great shelves!
Color: Grey, Size: 55 Inch, Style: 2 Pack
This shelf is lovely--simple and modern. My handyman said it was easy to install AND made a note to buy it for his own rental units because he said the internal supports were very sturdy. Fast delivery and exactly as described--and the price is nice, too.

Open kitchen concept came alive ❤️
Love these shelves and recommend to others. They are sturdy with the mounting bracket system and look great. It was easy to install with another set of hands. The material has the look I wanted and there were no missing parts!
