ECS Carbon Fiber Turbo Inlet Pipe for Audi B9 RS5 - The Ultimate Upgrade
Unlocking Performance with the ECS Turbo Inlet Pipe
The Audi B9 RS5 is an impressive machine, boasting a 2.9 TFSI twin-turbo engine that delivers 444 HP from the factory. However, the stock turbo inlet pipe—constructed from mandrel-bent, crushed steel—creates a bottleneck that limits airflow to the turbochargers, reducing the engine's full performance potential.
To address this, ECS has engineered a high-flowing, divorced turbo inlet pipe that maximizes airflow while maintaining stock-like fitment. Through the use of Computational Fluid Dynamics (CFD) software, premium carbon fiber, and billet aluminum components, ECS has developed the ultimate turbo inlet upgrade for the B9 RS5.
Key Features of the ECS Carbon Fiber Turbo Inlet Pipe
Lightweight and High-Quality Carbon Fiber Construction
- Crafted from 2x2 twill weave carbon fiber with a high-gloss clear coat for durability and aesthetics.
- Reduces weight by over 60% compared to standard aluminum or steel inlet pipes.
- Adapts to the stock system using precision-machined billet aluminum flanges with pre-installed captive O-rings for a seamless fit.
Modular Compatibility for Maximum Flexibility
- Compatible with both the factory airbox assembly and the ECS Luft-Technik Performance Intake System (ES#4213158).
- Ensures easy upgradeability or a return to the OEM setup without compatibility issues.
Optimized Airflow with Divorced Inlet Design
- Unlike standard non-divorced inlets, the ECS Carbon Fiber Turbo Inlet Pipe features an internal central vein that ensures each turbocharger receives equal airflow.
- CFD analysis showed that a non-divorced design causes a 50% airflow imbalance between the turbochargers, while ECS's divorced-style inlet reduces this difference to just 24%.
Performance Gains: By the Numbers
| Feature | OEM Spec | ECS Spec | Improvement |
| Overall Inlet Inner Diameter | 2.61" (66.5mm) | 3.05" (77.5mm) | +16.5% |
| Turbocharger Inlet Inner Diameter | 1.88" (48mm) | 2.19" (55.5mm) | +15.6% |
| Overall Weight | 2.82 lbs | 0.97 lbs | -65.6% |
| Airflow (@12 in/H2O) | 325 CFM | 400 CFM | +23% |
These figures highlight the ECS Turbo Inlet Pipe’s ability to improve airflow, reduce restriction, and optimize turbocharger performance for greater efficiency and power output.
Additional Performance Features
- Modular design ensures perfect fitment with both stock and aftermarket intake systems.
- Precision-machined billet aluminum turbocharger adapters with captive O-rings provide easy installation and a secure, leak-free connection.
- Divorced inlet setup balances airflow to both turbochargers for improved efficiency.
- Maximizes underhood space while retaining a factory-like fitment for a seamless upgrade experience.
- Integrated mounting flanges retain the factory harness clip points, ensuring hassle-free installation.
