Hey there, fellow Audi enthusiasts! If you're looking to give your B9 S4 or S5 a serious boost, let me tell you about the APR Full Intake System. This isn’t just some shiny part to slap on your engine; it’s a complete overhaul of your intake setup that actually makes a difference. We're talking about a system that’s designed for the 3.0T EA839 engines in the Audi S4 (2018-2025) and S5 (2018-2024), and it’s built to maximize airflow and turbo efficiency.

What sets this intake apart? For starters, it replaces everything from the inlet scoop down to the turbocharger inlet. No more bottlenecks where the factory parts choke off your engine’s potential. With this setup, you’re getting a whopping 31% more airflow compared to stock—525 CFM versus the factory’s 400 CFM at 28” H2O. That’s a serious upgrade that translates into real power. On my tuned S4 with APR Stage 1 (93), I saw gains of +19 AWHP and +20 AWFT-LBS of torque just by swapping to this intake. It’s like giving your turbocharger a breath of fresh air.

The design is smart too. APR uses thin-walled, heat-resistant composite materials to keep the weight down while maximizing the internal diameter. That means you get better airflow without compromising on durability. Plus, the PEX airbox shields the filter from engine heat, and the cutouts in the design help with airflow and give your engine that sweet sporty sound without being obnoxious.

Speaking of the filter, it’s a massive 7" x 7" pleated cotton gauze that’s washable, so you don’t have to keep buying replacements. It’s got a 5.5" frontal inlet and a 4" outlet, which means it’s not just about looks—this thing is built for performance. And if you’re planning on future upgrades, the billet turbo inlet adapter means you can easily accommodate larger turbos down the line.

Installation is a breeze too. The kit comes with all the gaskets, clamps, and hardware you need, so you can bolt it on without any fuss. And don’t worry about emissions; this system is compliant and doesn’t require any tuning. It’s emissions-friendly, so you can install it and hit the road without a second thought.

So, if you’re serious about unlocking your Audi’s full potential and want to feel the difference in power and responsiveness, the APR Full Intake System is the way to go. It’s not just another part; it’s a game changer for your ride.
