Unlock massive airflow gains and improved turbo induction sounds with the Unitronic 4" Carbon Fiber Intake System designed for vehicles equipped with the 2.5 TFSI EVO engine. This intake system is engineered to deliver increased horsepower, faster turbo spool, and improved throttle response, all while enhancing the visual appeal of your engine bay with its premium carbon fiber construction.

Fitment:

• Compatible with: Audi RS3 (2017-2023)
• Compatible with: Volkswagen Golf R (2019-2023)
• Engine Compatibility: 2.5 TFSI EVO (DAZA & DNWA)

Note: For 2019+ vehicles with the DAZA engine, please purchase the MY19+ Intake Adapter (sold separately) for seamless installation.

Key Features:

• 4" Carbon Fiber Tubing: The Unitronic intake features 4" carbon fiber tubes with a 2/2 twill prepreg carbon weave, delivering both lightweight performance and stunning aesthetics. The autoclave construction ensures the carbon fiber is strong, durable, and resistant to heat.

• Massive Airflow Gains:
  Testing on Unitronic’s Superflow SF-1020 Flow Bench showed a massive 88% increase in airflow over the OEM intake when using the Race Filter (1118 CFM vs. 595 CFM). Even with the Sport Filter, airflow gains were 84% (1095 CFM vs. 595 CFM). These gains result in better turbocharger performance, reduced turbo lag, and improved engine response.

• High-Quality EPDM Silicone Couplers:
  The intake system features Unitronic’s high-quality EPDM silicone couplers, which offer superior flexibility while maintaining strength and durability. The non-collapsing structural rib profile ensures that these couplers maintain their shape and allow for smooth, laminar airflow, reducing turbulence for improved engine efficiency.

• Optimized Airflow Design:
  Unitronic’s engineers used CFD (Computational Fluid Dynamics) to validate airflow efficiency across a range of conditions. The intake is designed for smooth, uninterrupted airflow to the turbo, allowing it to operate at peak performance levels with minimal stress.

• Direct Bolt-On Fitment:
  The Unitronic intake is a direct replacement for the OEM system, with no cutting or modifications required. It fits seamlessly into the engine bay, maintaining all OEM mounting points and offering a quick and easy installation process.

• Enhanced Turbo Induction Sound:
  The 4" intake tube, paired with the high-flow filters, amplifies the turbo’s characteristic spool and blow-off sounds, giving your vehicle a more aggressive and exciting performance note.

Airflow Performance:

Unitronic engineers validated the system’s effectiveness using the Superflow SF-1020 Flow Bench, resulting in:

• OEM Flow Rate: 595 CFM at 28" of H2O (Aq)
• Unitronic Flow Rate (Race Filter): 1118 CFM – 88% increase
• Unitronic Flow Rate (Sport Filter): 1095 CFM – 84% increase

These airflow gains lead to more efficient turbo operation, improved engine breathing, and enhanced throttle response, ensuring your 2.5 TFSI EVO engine performs at its best.

Hardware Included:

• 4" Carbon Fiber Air Intake Tube
• Carbon Fiber Transition Tube
• High-Flow Air Filters (Race and Sport options)
• High-Quality EPDM Silicone Couplers
• All Necessary Hardware (including stainless steel hose clamps)

Recommended Software:

For optimal performance, it is recommended to pair the Unitronic 4" Carbon Fiber Intake System with Unitronic ECU tuning:

• Stage 1 Tuning
• Stage 1+ Tuning
• Stage 2 Tuning

These custom software calibrations ensure that the intake system’s airflow gains are fully utilized, optimizing engine performance and boosting overall power output.

Installation:

• Installation Time: Approximately 1 hour
• Installation Difficulty: Easy – Direct bolt-on fitment
• Tools Required: Basic hand tools (screwdriver, socket set)
• Note: For 2019+ models with DAZA engines, please purchase the MY19+ Intake Adapter separately to ensure seamless fitment.

The installation process is straightforward and doesn’t require cutting or modification to any components. Simply remove the OEM intake, and bolt in the Unitronic 4" Carbon Fiber Intake in place.
