Competition Package – Water & Intercooler
Audi RS4 B9 & RS5 F5 · 2.9 TFSI
Holistic cooling concept for the V6 biturbo – developed for maximum thermal stability, constant power output and highest durability in the Audi RS4 B9 & RS5 F5.
Description
The Competition Package for the Audi RS4 B9 & RS5 F5 with the 2.9 TFSI biturbo engine combines a high-performance intercooler with an enlarged engine radiator to create a fully optimized cooling system. The aim is to ensure consistent control of all relevant temperatures – intake air and coolant – even under sustained high-performance driving conditions and with performance-enhancing modifications.
Technical benefits
- Significantly reduced intake air temperatures
- Noticeably more stable coolant temperatures under load
- Constant power output without thermal protection control
- Increased knock resistance at increased boost pressure
- Maximum thermal reserves for high-performance setups
System structure
- Performance intercooler with increased cooling volume
- High-performance engine water cooler with optimized core structure
- Flow-optimized aluminum end tanks
- High air and coolant flow rate with minimal resistance
- Vehicle-specific plug-and-play integration
Driving performance & stability
- Consistent performance during repeated full-load driving
- Reduced thermal stress on the engine and turbochargers
- Increased safety at high outside temperatures
- Optimal basis for Stage 2 and Stage 3 concepts
compatibility
- Audi RS4 B9 & RS5 F5 – 2.9 TFSI
Area of application
Developed for sporty road vehicles, performance-optimized Stage 1 to Stage 3 conversions, and vehicles with high continuous thermal stress. Especially recommended for software, exhaust system, and turbocharger modifications.
Notes
Installation should only be carried out by a qualified specialist workshop . After installation, the cooling system must be completely bled and a functional and leak test performed.
