APR 17-25 Audi A4/A5 (B9) 2.0T Carbon Fiber Intake System

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.
