Turbo Kit Billet Wheel Audi S4 RS4 RS6

The K04 Hybrid Turbo Kit with Billet Wheel is an advanced aftermarket upgrade designed to significantly enhance the performance of the Audi S4 RS4 2.7T, A6 2.7T, RS6T, and RS6 models. This kit replaces the stock turbochargers with hybrid units featuring billet compressor wheels, offering improved airflow, boost response, and overall engine efficiency.

**Materials and Construction:**

Turbochargers in this kit are typically constructed with high-quality materials, including billet aluminum for the compressor wheel. Billet wheels are CNC-machined from a solid piece of aluminum alloy, offering superior strength, durability, and resistance to heat and rotational stress compared to traditional cast wheels.

**Design and Features:**

1. **Hybrid Turbo Design:** The K04 Hybrid Turbo utilizes a combination of upgraded components from the original K04 turbocharger. This includes larger compressor wheels with advanced aerodynamics for increased airflow and efficiency.

2. **Billet Compressor Wheel:** The billet compressor wheel is a key feature of the hybrid turbocharger. Its design allows for higher rotational speeds and better durability, resulting in improved turbo spool-up and higher boost levels without compromising reliability.

3. **Enhanced Turbine Housing:** The kit may include upgraded turbine housings to accommodate the larger compressor wheel and improve exhaust gas flow. This optimizes turbocharger response and enhances overall engine performance.

4. **Performance Specifications:** Depending on the specific configuration, the K04 Hybrid Turbo Kit may offer substantial increases in horsepower and torque over the stock turbochargers. This upgrade is particularly favored among enthusiasts seeking to maximize the potential of their Audi’s 2.7-liter twin-turbo V6 engine.

**Compatible Year Models:**

– **Audi S4 B5 (1997-2002):** Includes the Audi S4 B5 models equipped with the 2.7-liter twin-turbocharged V6 engine, known as the 2.7T.

– **Audi RS4 B5 (2000-2001):** Specifically compatible with the high-performance Audi RS4 B5 variant, also powered by the 2.7T engine.

– **Audi A6 C5 (1999-2004):** Compatible with the Audi A6 C5 models equipped with the 2.7T engine, offering enhanced performance for both sedan and Avant (wagon) variants.

– **Audi RS6 C5 (2002-2004):** Designed for the high-performance Audi RS6 C5, featuring the 2.7T engine and offering significant power gains over the standard model.

**Performance Benefits:**
