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.

Medium size preferred.

I purchased both the large 4" and the medium 3" balls. My 80 lbs German shepherd much prefers the medium size. Show loves to play fetch with it and its lasted well!

Do not buy these
Color: Nude, Size: Women 9-13
These are terrible. They are designed to walk in. The first day I tried them on I walked about 20 steps and they basically ripped right off my feet. I didn’t think much of it and just thought ok I won’t walk in them I’ll just wear them to bed. The second pair that came with the order I wore to bed that night and woke up with holes tore in them. Terrible product

These are form-fitting and durable. Wearing these keeps the skin moisturizer in place so it can be effective.
