Bar-Tek 2.0L TFSI V1 Tuning Kit K04 is a tuning package for 2.0 TFSI engines, positioned between the standard solution and heavier V2/V3 level upgrades. The V1 level K04 configuration is designed for situations where the stock turbocharger and related components limit performance, but the goal is still a controlled load level and good long-term reliability.

The package is based on a component combination defined by Bar-Tek, where the turbocharger, exhaust manifold, air intake, and fuel delivery are dimensioned to work together with the K04 turbocharger without individual parts becoming bottlenecks in the system.

Delivery content

• K04 type upgrade turbocharger (V1 specification)

• K04-compatible exhaust manifold

• High-flow air intake / air filter solution

• Pressure management component (recirculation / diverter valve)

• Larger fuel injectors for K04 use

• Necessary adapter and installation parts

(Exact content is determined by engine code and vehicle-specific configuration according to Bar-Tek's specifications.)

Technical Overview

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

The package is constructed so that the parts work in balance together and support the use of the 2.0 TFSI engine in both street and enthusiast environments.

Compatibility

Suitable for 2.0 TFSI engines in several VAG Group vehicles, including:

• Audi A3 / S3

• Audi A4 / A5 2.0 TFSI

• Volkswagen Golf GTI

• Seat Leon Cupra

• Škoda Octavia RS

Compatibility must always be confirmed based on the engine code and vehicle-specific equipment before ordering.
