The Engineering team at ECS Tuning has spent countless hours in the development of the exclusive Audi B9 S4 3.0T Kohlefaser Luft-Technik (Carbon Fiber Air Technology) Cold Air Intake System. This intake was precision engineered using state of the art laser scanning, dyno testing, and 3D CAD technology to combine factory-like fitment in your engine bay with increased engine performance.

This intake is crafted of high quality hand laid carbon fiber with a fiberglass interior layer to achieve world class appearance and durability while resisting the performance robbing effects of heat soak. The turbo inlet hose is crafted of a high quality 4-ply silicone to achieve increased durability and resistance to collapsing.  We also include a bellmouth (velocity stack) filter flange inlet to reduce turbulence and maximize flow.

This intake has been subjected to rigorous real world testing with verified performance gains on our in-house chassis dyno resulting in an increase of 16WHP and 15WTQ with the factory tune. The increase in turbocharger spool noise during heavy acceleration is an enthusiast's dream, giving hint to the added performance without being too intrusive. The end result of all of this effort is an intake system that combines fitment, quality and performance into one stunning package that will make a statement in your engine bay.  

The ECS Tuning Kohlefaser Luft-Technik Intake System features:

• Specifically crafted to fit Audi B9 S4 3.0T engines, from the 2018+ MY, using all stock mounting locations
