The Bar-Tek 2.0L TSI EA888 V1 Tuning Kit K04 is a tuning package for 2.0 TSI EA888 engines, clearly positioned between the standard solution and the heavier V2/V3 configurations. The V1 level K04 solution is designed for use where the stock turbocharger and related components become limiting factors, but the goal is not yet the most extreme power level.

The package is based on component selection defined by **BAR-TEK**, where the turbocharger, exhaust side, air intake, and fuel delivery are sized to work together with the K04 turbocharger at a controlled load level.

Delivery Content

• K04-type upgrade turbocharger (V1 specification)

• K04-compatible exhaust manifold

• High-flow air intake / air filter solution

• Boost management component (recirculation / diverter valve)

• Larger fuel injectors for K04 use

• Necessary adapter and installation parts

(The exact content is determined according to the EA888 version and vehicle-specific configuration as per Bar-Tek's specifications.)

Technical Configuration

In the V1 level K04 configuration, the turbocharger's capacity is increased above the standard solution while maintaining a moderate overall load on other engine components. The exhaust manifold and air intake are chosen to support the K04 turbocharger's operation without unnecessary flow restrictions, and the fuel system is sized to meet increased demands.

The package is built so that the parts support each other without obvious bottlenecks and maintain the EA888 engine's usability and long-term reliability.

Compatibility

Suitable for 2.0 TSI EA888 engines in several VAG group vehicles, including:

• Audi A3 / S3

• Volkswagen Golf GTI

• Seat Leon Cupra

• Škoda Octavia RS

Compatibility must always be verified based on the EA888 version (V1), engine code, and vehicle-specific equipment before ordering.
