APR PEX Full Intake System for Select 2018-2024 Audi S4 / S5 (3.0T) - CI100072

Fits select 2018-2024 Audi S4 and S5 models, including Sportback (3.0T EA839).

The APR PEX Full Intake System is a comprehensive induction solution designed to maximize airflow and turbocharger efficiency on the B9/B9.5 3.0T platform. Unlike partial intake upgrades, this kit replaces every component from the radiator support inlet scoop to the turbocharger inlet. By utilizing a thin-walled, heat-resistant composite material for the turbo inlet pipe, APR maximizes internal diameter within the cramped engine bay, resulting in a 31% increase in airflow over the factory system (525 CFM vs. 400 CFM).

This system eliminates factory restrictions to improve throttle response and reduce pressure drop, allowing the turbo to spool faster. On Stage 1 (93 octane) equipped vehicles, this intake has demonstrated gains of +19 AWHP and +20 AWFT-LBS. The PEX airbox design features a heat-shield configuration with integrated flow paths for cooler air intake, while the massive 7-inch washable filter ensures superior filtration and longevity.
