If you’re looking to give your Audi A4 or A5 (B9) with the 2.0T EA888 Gen 3 or Gen 4 engines a serious boost, this intake upgrade is the way to go. I’ve had the chance to install it on my own ride, and let me tell you, the difference is real. It flows a whopping 46% more air than the stock setup, which means less pressure drop and a turbo that’s just itching to spool up faster. You can actually feel the extra horsepower and torque when you hit the gas, and it’s an upgrade that won’t break the bank.

This isn’t just a simple add-on; it’s a complete overhaul of your intake system. From the inlet scoop right down to the turbo inlet, every component is replaced. The whole setup is crafted from PEX, which not only looks sharp under the hood but also lets us keep the tube walls thin. This maximizes the internal diameter for even better performance. Plus, the flexibility of PEX means we can create some complex shapes that fit snugly in that tight engine bay.

The airbox is designed to maximize airflow, featuring an inlet scoop that directs air straight into it. There are even cutouts to help guide additional airflow away from the engine, which helps keep air temperatures down and gives your engine that nice growl without being obnoxious. And let’s not forget the T304 stainless steel heat shield that keeps the heat from the engine bay away from the turbocharger, ensuring cooler intake temperatures.

Now, let’s talk about the filter. It’s huge—measuring 7” by 7” with a 5.5” frontal inlet and a 4” outlet. A larger filter means more surface area, which helps it breathe easier for a long time, filtering out dirt and dust without a hitch. The filter is made of washable pleated cotton gauze, so you can clean it and keep using it for miles, or swap it out when it’s time.

Installation is a breeze, too. You’ll get all the clamps you need to bolt it on and go, and there’s no new tuning required. Plus, it’s emissions-friendly, so you won’t have to worry about any compliance issues. This intake fits a range of models: Audi A4 (2017-2018), A4 Allroad (2017-2024), A5 Quattro (2018-2024), and A5 Sportback (2018-2024).
