Stage III+ for the B6 A4 is being released initially with only stock, 91, and 93 octane programs. Race gas 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 93 octane, as APR is not responsible for this type of damage to the engine.
For all 02-05 1.8t A4s
