CTS Turbo is proud to announce our new intake system for the B9 AUDI A4, AllRoad, A5, S4, S5, RS4, RS5 (2017-2021 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!
  • Kit comes with parts to install on 1.8T, 2.0T, 2.9T and 3.0T engines (fits MAF-LESS cars)

About this Cold Air Intake

The CTS TURBO CTS-IT-290R air intake system replaces the factory airbox and intake tube to let the engine breathe more freely. Intakes typically bring a sportier induction sound and can improve throttle response, especially on turbocharged engines.

Frequently asked questions

How much power does an intake add?

Gains vary with the engine and are usually modest on a stock car; turbocharged engines and cars with other modifications tend to benefit more. Many buyers choose an intake as much for the sound and response as for power.

Is this intake legal in California?

In California and states that follow its rules, an aftermarket intake must have a CARB Executive Order (EO) number for the specific vehicle to be street legal. Check the product details for an EO number before buying for road use in those states.

Will an intake cause a check-engine light?

A quality intake designed for your car should not. Problems usually come from a poorly sealed connection, a damaged sensor, or over-oiled filters contaminating the mass air flow sensor.

How do I maintain the filter?

Inspect it regularly. Reusable filters can be cleaned and, if they are oiled, re-oiled lightly using the maker's kit. Dry filters can be cleaned or replaced according to the maker's instructions.

How do I make sure this air intake system fits my car?

Compare the part numbers listed on this page with the number on your old part or in your vehicle's parts catalog, and check the fitment information. If you are unsure, contact us with your VIN before ordering.
