Description
Overview
The AWE Tuning S-FLO Carbon Inlet Tube delivers 4.5″ of pure carbon power to the Audi 8V RS3 and Mk3 TT RS. Engineered as the largest inlet tube amongst its peers, this carbon fiber cold air intake tube bridges the gap between the turbo inlet pipe and the factory airbox seamlessly, giving your 2.5-liter, AWD platform a cleaner, less restrictive path for airflow. For drivers looking to extract the most from their factory airbox while sharpening throttle response, the S-FLO Carbon Inlet Tube is a purposeful, precisely-engineered upgrade.
Key Benefits
The colossal 4.5″ diameter is the headline here: more cross-sectional area means impressive adaptability to facilitate maximum gains from the components you already run. Because it’s designed to maximize the potential of your factory airbox, you get improved throttle response and a more responsive feel without reinventing your entire intake tract. It’s built from carbon fiber for a premium look and finish that stands out under the hood, and it arrives with the hardware needed to get the job done.
- Massive 4.5″ carbon fiber inlet tube — the largest amongst its peers
- Bridges the factory airbox and turbo inlet pipe seamlessly for maximized airflow
- Increases throttle response by opening up the factory airbox’s potential
- Includes a 4.5″ to 3″ coupler to mate to the factory 3″ turbo inlet pipe
- Hardware included, with a Fit Guarantee and No CEL Guarantee
- No tune required to install and run
Options & Compatibility
The S-FLO Carbon Inlet Tube comes complete with a 4.5″ to 3″ coupler to mate directly to the factory 3″ turbo inlet pipe, making it a natural fit for stock-turbo-inlet setups. If you’ve already stepped up to an aftermarket turbo inlet pipe measuring 4″ in diameter, the S-FLO 4″ Coupler transitions from 4.5″ to 4″ to accommodate it and is available separately (SKU: 7260-11002). Choose the coupler configuration that matches the turbo inlet pipe on your car.
Built to Grow With Your Build
The S-FLO Carbon Intake Suite is modular by design, so the inlet tube isn’t a dead end — it’s a starting point. That means an easy evolution from the S-FLO Inlet Tube or S-FLO Shortie Carbon Intake all the way to the full S-FLO Carbon Intake Systems (open or closed) as your build progresses, protecting your investment along the way.
Fitment
This S-FLO Carbon Inlet Tube is engineered specifically for the Audi 8V RS3 and Mk3 TT RS (Coupe/Sedan, 2.5, AWD). It carries a Fit Guarantee and a No CEL Guarantee, requires no tune, and is supplied with the required hardware. Note the voluntary CARB Restricted label applies to this air intake component.
