APR PEX Cold Air Intake For Audi A4/ A5 (B9) 

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.
