The APR Closed Carbon Fiber Intake System is an attractive, high-performance upgrade designed to increase performance by letting the engine breathe more freely. Performance is optimized by improving mass airflow through the system, while also adequately filtering the incoming air. The system provides a direct airflow path through the system to the filter, and removes the rubber inlet snorkel, which has been known to collapse under load, and devastate power deliver. Expect increased horsepower, torque, sharper throttle response, enhanced fuel economy, enhanced engine sound, lower intake air temperature (IAT) and a more attractive engine bay! Lastly, 3.0T Supercharged engine customers can take advantage of a larger rear charger inlet pipe, which maximizes mass airflow, and removes a factory sound dampening resonator. , , Power Gains, Using the upgraded air box alone, the 3.0T engine picked up 11 AWHP, and 15 AWHP when adding the rear inlet pipe. This was achieved at only Stage 1 power levels. As airflow requirements increase, so does the potential for more power. Likewise, on the 4.2L FSI V8 we measured 10 HP through the rev range on an otherwise stock vehicle.
