Audi 2.0/1.8 TFSI & 2.0 TDI Carbon Fibre Cold Air Intake System - CI100021

Home > Audi > A4 & S4 (B8)

Carbonio's latest carbon fibre intake for the 2.0/1.8 TFSI & 2.0 TDI engine is a ram air design that completely separates the intake filter from the engine bay. Building from years of experience on and off the race track, Carbonio's and APR's engineering teams have spent countless hours developing a true cold air and ram air carbon fibre design that can be recreated affordably for the street performance enthusiast.

For many years professional motorsport organisations have suffered great expense to properly tune the air intake delivery system for turbocharged engines for use in endurance and sprint races where every last horsepower and pound feet of torque can make the difference in position when crossing the finish line. Historically these designs have proven to be the most efficient and powerful although the most expensive to produce.

Aftermarket performance companies have attempted to capitalise on these designs however the cost restraints have typically resulted in compromise and deviation from the true engineering principles associated with motorsport accomplishment. Don't be fooled by catch phrases and tag lines alluding to a new intake technology or special design characteristic. You won't see any of these gimmicks installed on race cars at the Nurburgring.

Carbonio and APR have gone even further to maintain all OEM specifications necessary to integrate cohesively with an otherwise stock engine to avoid raising eyebrows at the dealership. Flexibility was another characteristic of Carbonio's and APR's design whereas the new TFSI intake is also suitable for Stage 1 and Stage 2 modified engines all the way up to and beyond APR's K04 Turbocharger System.

Constructed of aerospace grade carbon fibre and designed to remove intake restriction, APR’s Carbonio intake system provides smoother transitional airflow, increased air velocity, superior insulation of the incoming air to reduce intake air temperatures and a larger volume of available air to aid throttle response and turbocharger spool.

Smooth and Direct Air Flow

The OEM intake system vents some of the incoming air into the engine bay and takes several twists and turns before the air ever reaches the turbocharger. The Carbonio intake system simplifies the intake system by directing all incoming air directly at the filter.

Benefits of the Carbonio CAI System include:

  • Increased Horsepower and Torque
  • Improved Throttle Response
  • Decreased Turbo 'Lag'
  • Improved Fuel Economy
  • Enhanced Engine Volumetric Efficiency
  • Enhanced Sound of Turbo Diverter Valve
  • Installs in an Hour (does not require bumper or headlight removal)
  • Maintains Clean Appearance by Retaining Factory Engine Cover
  • Maintains All Factory Emissions Components
  • Fits Both Manual and Automatic Transmissions
  • Fully Compatible and Complimentary, with APR Software and Exhaust systems
  • Maintains the Thermostatically Controlled OEM Flap Valve Assembly from the Factory Airbox
