This is the perfect intake upgrade for the Audi A4 and A5 (B9) with the 2.0T EA888 Gen 3 and Gen 4 engines. It flows 46% more than stock, reduces pressure drop, and improves turbocharger efficiency. This directly translates to more horsepower and torque making this a simple upgrade for more power you can feel, and does so at an incredible value. Our system is a full upgrade as it replaces all of the intake components from the inlet scoop all the way to the turbo inlet. Our system is made from PEX and looks great under the hood, matching the texture of other components. By using this material we are able to make the wall-thickness of the tubes small, maximizing the internal diameter, increasing performance even more! The material also allows us to make complex organic shapes necessary when working in a tight engine bay. The airbox is fed from an inlet scoop that maximizes the flow path into the airbox. The airbox has cutouts allowing for additional flow paths directed away from the engine. This keeps air temps down, and increases sound without it being overbearing. Furthermore we've incorporated at T304 stainless steel heatshield to keep hot engine bay heat from the turbocharger away from the airbox. The filter is massive as well. A big filter is desirable as increasing filtered surface area keeps the filter breathing easily for many miles as it filters dirt, dust, and particles. It measures 7" by 7" with a 5.5" frontal inlet, and a 4" outlet. The filter media is a washable pleated cotton gauze that can be cleaned for extended life, or replaced with ease. Our kit includes everything you need to bolt on and go. No new tuning is needed to run this product, and the product is emissions friendly. We include all new clamps needed for an easy install.

    I have been trying to look for a legal cold air intake for a while, and I want to know if this intake is legal in New York State. Please let me know, thank you.

    We have emissions tested this product and it passed all tests. Please see our emissions section for exact emissions classifications.
  • Question

    I was looking really hard for a CARB approved cold air intake, and it seems I have finally found on here on your website. Is this intake legal in the state of New York? Thank you!

    By Dylan on February 10, 2023

  • Question

    is there a date in which we will know if it passes CARB testing

    By Rubio.M on June 13, 2023

    We don't have that information. It's a long process.

The factory intake simply can’t match the performance of ours. The factory system flows a maximum of 478 CFM at 28” in of H2O. We improve this by 46% as our full intake system flows 699 CFM! We’ve reduced pressure drop across the system and improved turbocharger efficiency. The turbo spools faster, and operates in a more efficient region of the compressor map. This directly translates to more power and torque you can feel.
