If you’re looking to seriously up your game with your Audi RS4 or RS5 (B9) 2.9T, the APR Full Intake System is where it’s at. This isn’t just another intake; it’s a complete overhaul of your factory setup, designed to maximize airflow and turbo performance. Trust me, I’ve seen the difference it can make firsthand.

What sets this system apart is its all-in-one approach. While other intakes might only tackle a part of the system, this beauty replaces everything from the inlet scoop right down to the turbocharger inlet. That means no more bottlenecks—just pure, unrestricted airflow. And let’s be real, more airflow means better turbo efficiency and, ultimately, more power. We’re talking about a solid 31% increase in airflow compared to stock. That’s not just numbers; it translates to an impressive +19 AWHP and +17 AWFT-LBS of torque on my APR Stage 1 (93) tuned RS5.

The design is smart, too. APR uses thin-walled, heat-resistant composite materials to create a larger internal diameter, which is crucial given the tight space in the engine bay. The PEX airbox cleverly shields the filter from engine heat while incorporating cutouts that help with airflow and give your engine that refined sound we all crave. And let’s not forget the massive 7" x 7" washable pleated cotton gauze filter—it’s got a huge surface area for superior filtration and lasts a long time before needing a clean.

One of the standout features is how the APR Full Intake System drastically improves turbocharger efficiency. The stock intake flows a maximum of 484 CFM at 28" H2O, but this system cranks that up to a whopping 658 CFM. That’s a 36% improvement that you can feel when you hit the gas. Plus, it reduces the pressure drop, allowing the turbo to spool up quicker and operate more efficiently. It’s power you can actually feel in the seat of your pants.

And if you’re thinking about future upgrades, this system has you covered with a billet turbo inlet adapter that can accommodate larger turbos with just a simple swap. The installation is straightforward, too, as it comes with all the OEM gaskets, clamps, and hardware you need. Best of all, it’s emissions-friendly and doesn’t require any tuning, so you can keep it compliant while enjoying that sporty, refined engine sound without it being over the top.

In short, the APR Full Intake System is the real deal for anyone serious about unlocking their Audi's potential. It’s built for performance, functionality, and durability—everything you’d expect from a product designed by people who know and love these cars.
