The Ultimate Titanium Intake for the 2.9T/3.0T Turbocharged V6.

The CAP V2 Titanium Intake for the B9 Audi S4, S5, RS4, and RS5 is the premium evolution of our performance intake system. Engineered to move more air, more efficiently, it combines class leading airflow with lightweight titanium construction and an unmistakable motorsport inspired appearance.

Developed using advanced CFD analysis, 3D scanned engine bay modeling, and real world testing, the CAP V2 Titanium Intake delivers measurable performance gains while setting a new benchmark for airflow capacity, sound, fitment, and finish.

The system features the largest air filter and largest velocity stack available for the B9 platform, maximizing airflow volume while maintaining smooth, high velocity air delivery to the turbocharger. The result is improved throttle response, faster boost onset, and stronger performance throughout the RPM range, with no tune required.

Two Titanium Finishes

Choose the titanium finish that best complements your build:

• Ghost Titanium: A clean brushed titanium finish created for an OEM+ appearance. Ghost delivers the exotic appeal of titanium with a sophisticated finish that matches that of a supercar.

• Phoenix Titanium: A bold burnt titanium finish featuring vibrant heat treated colors. Phoenix transforms the engine bay with an unmistakable motorsport inspired appearance.

Both variants use the same performance focused titanium construction and deliver identical airflow, sound, fitment, and durability.

What Makes Titanium Superior?

Every CAP titanium intake is designed to take advantage of the material’s low weight, strength, heat resistance, and corrosion resistance. Its low thermal conductivity helps limit heat transfer through the intake tube, while its strength allows it to withstand demanding driving conditions without compromising durability.

Beyond its performance benefits, every titanium intake has a distinctive finish and character that cannot be replicated by conventional materials. The result is a performance intake with exotic looks and an exciting turbocharged sound every time you open the hood or press the throttle.

What Sets the CAP V2 Titanium Intake Apart

• Massive 7 Inch Performance Air Filter
  Featuring 50% more surface area than leading competitor options, the oversized filter supports extreme airflow demands without sacrificing filtration efficiency.

• CAPFlowMax Proprietary Filtration Technology
  Developed exclusively for this intake, CAPFlowMax balances maximum airflow with superior filtration. This allows clean air to reach the turbocharger with minimal restriction while maintaining dependable engine protection.

• Largest Velocity Stack for the B9 Platform
  The largest and highest flowing velocity stack in its class smooths airflow as it enters the intake, increases velocity, and reduces turbulence for maximum performance at any power level.

• Premium Titanium Construction
  Lightweight, corrosion resistant, and built to withstand extreme conditions, the titanium intake tube delivers lasting performance with an exotic appearance.

Engineering and Development

• CFD Optimized and Flow Tested: Designed using advanced airflow simulations and physical testing to deliver measurable gains backed by real engineering.

• 3D Scanned Engine Bay Modeling: Every millimeter of available space was evaluated to maximize airflow and ensure precise fitment.

• Smooth Internal Airflow Path: Carefully designed transitions help maintain consistent airflow and reduce turbulence on the way to the turbocharger.

• Multiple Design Revisions: Refined through numerous iterations to perfect airflow, sound, clearance, and installation.

• OEM Mounting Integration: Reuses the factory rubber grommets with CAP hardware for secure, factory quality mounting and filter isolation.

• Sealed Heat Shield Design: Weather stripping and an integrated bracket system help isolate the filter from engine bay heat while keeping the assembly securely in place.

Sound That Demands Attention

The CAP V2 Titanium Intake does more than improve airflow. It transforms the driving experience.

Expect aggressive turbo spool, sharper induction sound, and supercar level intake noise under load, all without sacrificing the comfort and drivability expected from your Audi.

Designed to Scale With Your Build

Whether your vehicle is stock, tuned, or being prepared for a future turbo upgrade, the CAP V2 Titanium Intake is engineered to support airflow demands well beyond factory levels.

Its oversized filter, high flow velocity stack, and unrestricted airflow path make it the last intake you will need for your B9 S4, S5, RS4, or RS5.

Turbo Inlet Fitment

This intake is designed to fit OEM sized turbo inlets only and is not compatible with aftermarket inlets that differ from the factory dimensions.

You can pair the intake with our improved CAP V2 Style Turbo Inlet, which was developed to complement the intake and provide precise fitment, smooth airflow, and maximum performance.

Lifetime Warranty

The CAP B9 S4, S5, RS4, and RS5 V2 Titanium Intake is backed by our CAP Lifetime Warranty, protecting your investment for as long as you own it.

Warranty Disclaimer: The air filter is considered a wear and tear item and is not covered under the lifetime warranty.
