The CAP V2 Intake for the B9 Audi B9 Audi A4/A4 Allroad, A5 is engineered with one goal: move more air, more efficiently, than anything else available for the platform. Designed from the ground up using advanced CFD analysis and validated through real-world testing, this intake delivers measurable performance gains while setting a new benchmark for airflow capacity, sound, and fitment.
Featuring the largest air filter and largest velocity stack available for the B9 platform, the CAP V2 Intake maximizes airflow volume while maintaining smooth, high-velocity air delivery to the turbocharger. The result is improved throttle response, faster boost onset, and stronger power delivery throughout the RPM range — all with OEM-level reliability and no tune required.
• Massive 7-Inch Performance Air Filter
Featuring 53% more surface area than leading competitor options, the oversized filter supports extreme airflow demand without sacrificing filtration efficiency.
• CAPFlowMax Proprietary Filtration Technology
Developed exclusively for this intake, CAPFlowMax balances extreme airflow with superior filtration, ensuring clean, dense air enters the turbocharger for consistent performance and long-term reliability.
• Largest Velocity Stack for the B9 Platform
The biggest and highest-flowing velocity stack in its class smooths airflow entry, increases velocity, and reduces turbulence — maximizing performance gains at any power level.
• CFD-Optimized and Flow-Tested – Designed using advanced airflow simulations to deliver proven performance gains backed by real engineering.
• 3D-Scanned Engine Bay Modeling – Every millimeter of available space is utilized to maximize airflow and ensure precise fitment.
• Multiple Design Revisions – Refined through numerous iterations to perfect airflow performance, sound, and installation.
• Built for Durability – Corrosion-resistant construction designed to last a lifetime, even under extreme driving conditions.
• OEM Mounting Integration – Reuses factory rubber grommets with CAP hardware for factory-like fit, filter isolation, and reliability.
• Sealed Heat Shield Design – Weather stripping, an integrated bracket, and a rubber mount designed to keep the heat shield securely mounted while isolating the filter from engine bay heat.
The CAP V2 Intake doesn’t just improve performance — it transforms the driving experience. Expect enhanced turbo sound, sharper throttle response, and a more aggressive induction note under load, all while maintaining comfort and drivability for daily use. CAP’s V2 intake is completely plug and play and does NOT require an engine tune.
Whether you’re stock, tuned, or planning future turbo upgrades, the CAP V2 Intake is engineered to support airflow demands well beyond factory limits — making it the last intake you’ll ever need for your B9 Audi A4/A5.
This intake is designed to fit OEM-sized turbo inlets only and is not compatible with aftermarket inlets that differ from factory dimensions.
You can pair this intake with our new and improved V2 Style Turbo Inlet, which is specifically designed to complement our intake perfectly, ensuring optimal fitment, smooth airflow, and maximum performance gains.
The CAP B9 Audi B9 Audi A4/A4 Allroad, A5 V2 Intake is backed by our CAP Lifetime Warranty, ensuring your investment is protected for as long as you own it.
