THE XS-POWER K04-001 PERFORMANCE UPGRADE FOR THE LEGENDARY VW / AUDI 1.8T
Looking for more than another ordinary K03 replacement? Step up to the XS-POWER Billet K04-001 EO5 50mm Turbocharger, built specifically for enthusiasts upgrading compatible transverse Volkswagen and Audi 1.8T applications.
At the heart of this turbo is the upgraded EO5 50mm billet compressor, giving the K04-001 platform increased performance potential while retaining the compact turbo configuration that made the K03/K04 family so popular on the VW/Audi 1.8T.
This is an excellent performance turbo upgrade for compatible VW Golf MK4 GTI, Jetta MK4, New Beetle 1.8T and Audi TT 180HP applications.

K04-001 turbo applications can vary by vehicle, engine code and original turbo configuration. Common transverse 1.8T applications include engine codes such as:
AWD • AWW • AWP • APH • ATC
Always verify the original turbo configuration, engine code, compressor inlet, exhaust connection and surrounding components before ordering.
The factory turbocharged 1.8T responds extremely well to properly matched airflow, fueling, exhaust and ECU calibration upgrades.
The XS-POWER Billet K04-001 gives builders a larger performance-oriented turbo option while maintaining the responsive characteristics enthusiasts want from a street-driven 1.8T.
Actual horsepower and boost capability depend on the engine condition, fuel quality, ECU calibration, exhaust, intercooling, intake system and supporting modifications.
- ECU calibration designed for the upgraded turbocharger
- Upgraded intercooler
- High-flow exhaust / downpipe
- Properly sized turbo inlet
- Healthy diverter valve and boost-control system
- Appropriate fueling for the intended tune and power level
- Fresh spark plugs and properly functioning ignition coils
Turbocharger includes the applicable gaskets. Turbo inlet pipe is NOT included.
Some applications require a larger turbo inlet pipe. For example, applicable Audi TT 180HP configurations such as the ATC application may require the larger inlet pipe. Verify your inlet configuration before installation.
