Discover the APR Full Intake System, specifically designed for the Audi S4 and S5 (B9) 3.0T EA839. This intake system is more than just a performance upgrade; it's a complete overhaul of your vehicle's airflow management, ensuring that you get the most out of your engine. Customers have shared their satisfaction, noting how this system has transformed their driving experience.

The APR Full Intake System replaces every component from the inlet scoop to the turbocharger inlet, eliminating any restrictions that could hold back performance. Unlike other systems that compromise by using factory-sized components, this intake maximizes airflow with a design that allows for the largest inlet possible. The result? A remarkable 31% increase in airflow compared to the stock setup, which translates into quicker turbo spool times and impressive power gains—specifically, +19 AWHP and +20 AWFT-LBS of torque when paired with our APR Stage 1 (93) tune on the S4.

One of the standout features of this system is the high-temperature composite turbo inlet, which uses thin-walled tubing to achieve maximum internal diameter and airflow. The PEX airbox not only shields the filter from engine heat but also incorporates strategically placed cutouts for enhanced airflow and a refined engine sound. The massive 7" x 7" washable pleated cotton gauze filter provides an extensive filtration surface area, ensuring long-lasting performance and easy maintenance.

Many users have remarked on the noticeable improvement in both power delivery and engine sound. One customer mentioned, "The installation was straightforward, and I could feel the difference immediately. The engine sounds fantastic without being too loud." This intake system is designed for those who want to unlock their vehicle's full potential without sacrificing emissions compliance, as it requires no tuning and meets emissions standards.
