Audi A4 S4 APR Turbocharger

APR is well known for developing performance upgrades for Audi and other Volkswagen Group vehicles. An APR turbo upgrade can be an important component of a larger performance build.

Depending on the specific turbocharger and engine application, an upgraded turbo may be paired with:

• APR ECU software
• High-flow intake
• Upgraded intercooler
• Performance exhaust
• Downpipe
• Upgraded fueling components
• Performance spark plugs
• Improved cooling system
• Supporting engine hardware

The correct supporting modifications depend on the exact Audi engine and APR turbocharger configuration.

Performance Turbo Upgrade

The main advantage of a larger performance turbo is increased airflow potential. More airflow can allow the engine to produce additional horsepower and torque when the engine management system and supporting components are properly configured.

A performance turbo can also provide improved high-RPM power compared with a smaller factory turbo.

For the best results, the turbocharger should be matched to the vehicle’s:

• Engine code
• Model year
• ECU calibration
• Fuel system
• Intake system
• Exhaust system
• Intercooler
• Transmission
• Intended power level

Audi A4 and S4 Fitment

This APR turbo upgrade may be suitable for specific Audi A4 and S4 applications.

Because Audi has used several different engines and turbocharger configurations across the A4 and S4 range, exact compatibility must be confirmed before ordering.

Please verify:

• Audi model and year
• Engine size
• Engine code
• Original turbocharger
• APR turbo part number
• ECU software
• Transmission
• Vehicle VIN

Do not assume this turbo fits every Audi A4 or S4. Exact fitment depends on the specific APR turbocharger and engine application.

Audi Performance Parts

An APR turbo upgrade works best as part of a complete performance package. Increasing turbocharger airflow without the correct software and supporting components can prevent the engine from operating as intended.

For a reliable performance build, consider matching the turbo with appropriate engine management, intercooling, intake, exhaust, and fueling upgrades.
