APR Stage III+ Kit 2001-2005 A4 B6
Engineered Performance for Audi, VW, Porsche & Skoda
APR announces the Stage III+ kit, the ultimate turbo system upgrade for the 2002-2005 A4 1.8T. This kit is capable of 254 Kw and 450 Nm of torque at the flywheel on 98 octane fuel, while retaining stock-like drivability. The highlights of the kit include the following:
- APR Investment Cast Inconel Exhaust Manifold
- Honeywell/Garrett Ballistic Series Ball-Bearing Turbocharger
- Larger APR designed Mass Airflow Sensor Housing
- APR Custom Cast Silicone Intake Hoses
- APR High Flow Fuel Injectors
- High Flow Catalytic converter & downpipe
- All Associate Plumbing and Hardware

Stage
III+ for the B6 A4 is being released initially with only stock, 95, and
98 octane programs. Race fuel programs will be available soon.
The power increase with the APR Stage III+ kit for the A4 1.8T is
substantial. It is highly recommended that brake and suspension
upgrades are done to safely use the potential of this upgrade. It is
also recommended that the stock engine internals be upgraded for power
levels above 98 octane, as APR is not responsible for this type of
damage to the engine.
