APR PEX Intake System - Audi A4 / A5 (B9) 2.0T 2017-2025

APR's PEX intake replaces every intake component from the inlet scoop through to the turbocharger inlet on the EA888 Gen 3 and Gen 4 2.0T, flowing 46% more than stock and cutting pressure drop so the turbocharger spools sooner and runs more efficiently. The PEX airbox and tubing hold a thin wall section that maximizes internal diameter while matching the texture of the surrounding factory parts, and airbox cutouts draw additional air from paths directed away from the engine to keep intake temperatures down. A T304 stainless steel heatshield blocks turbocharger heat, and the 7 in by 7 in filter with a 5.5 in frontal inlet and a 4 in outlet uses washable pleated cotton gauze media that can be cleaned or replaced. All required clamps are included, no retune is needed and the system is emissions friendly.
