8-Inch Velocity Stack Intake System

The CAP V2 Intake system, identified by MPN CAP-INT-013, is engineered for the B9/B9.5 Audi S4, S5, RS4, and RS5 (2017-2024). It boasts the largest velocity stack and an 8-inch air filter on the market for this platform, aiming to maximize performance gains by smoothing airflow entry, increasing air velocity, and minimizing turbulence. Developed with advanced Computational Fluid Dynamics (CFD) analysis and extensive flow testing, this intake system utilizes 3D-scanned engine bay modeling to ensure optimal use of available space and precise fitment. The design has undergone multiple revisions to perfect airflow, sound, and ease of installation. Constructed for durability with corrosion-resistant materials, it is built to last under demanding conditions. The system integrates with factory mounting points using OEM rubber grommets for reliable filter isolation and a secure installation, featuring a sealed heat shield with weather stripping to prevent engine bay heat intrusion. The CAP V2 Intake is designed to support airflow demands beyond factory limits, making it suitable for stock vehicles, tuned setups, or future big turbo upgrades. It enhances the driving experience with aggressive turbo spool sounds and sharp throttle response, delivering a supercar-level induction noise under load without compromising daily drivability. The intake is guaranteed not to cause a check engine light and comes with a lifetime warranty, though the air filter is considered a wear-and-tear item not covered by the warranty. Additionally, it does not fit cars equipped with a MAF sensor.
