Cold Air Intake for 1.4 TSI CAXA (EA111)

The Project R1 cold air intake system is designed to improve airflow efficiency and overall engine performance for Volkswagen Group vehicles equipped with the 1.4 TSI CAXA petrol engine from the EA111 engine family. This engine generation is known for its turbocharged design and strong tuning potential, but the factory intake system can become a restriction under increased load.

Compared to the OEM intake, the Project R1 cold air intake provides a smoother, less restrictive airflow path and a stable supply of cooler air to the turbocharger, resulting in improved throttle response and more efficient engine operation.

Designed for EA111 1.4 TSI Engines

This intake system is specifically engineered for EA111 1.4 TSI engines, including the CAXA engine code. EA111 engines use a turbocharged intake layout where airflow quality and pressure stability play a key role in performance and reliability.

The Project R1 intake is suitable for:

• Stock engines
• Stage 1 and Stage 2-3 tuned vehicles
• Daily-driven cars and performance-oriented setups

Key Features & Benefits

• Enlarged airbox volume for a stable reserve of cold air
• High-flow intake duct with smooth internal transitions to reduce turbulence
• Eliminates restrictive sections found in the OEM intake system
• Improved airflow to the turbocharger for better throttle response
• Reduced intake air temperature compared to the factory design
• Includes Project R1 high-flow performance air filter
• Direct bolt-on installation using factory mounting points
• No cutting or permanent modifications required
• Special rubber coupler replaces the restrictive OEM flex hose:
  • improves airflow consistency
  • reduces vibration
• Integrated drain holes in the airbox for condensate removal

Engine & Vehicle Compatibility

This cold air intake is designed for Volkswagen Group vehicles equipped with the 1.4 TSI CAXA engine (EA111 platform).

Compatible vehicles include (depending on configuration):

• Volkswagen Golf V / Golf VI 1.4 TSI
• Volkswagen Jetta V / Jetta VI 1.4 TSI
