Why This Sealed Carbon Fibre Intake Wins

The Audi B9 S4 and B9 S5 engine bays heat soak quickly. Open cone intakes can ingest hot air, raising IATs and costing power. Eventuri solves this with a fully sealed carbon fibre intake from the front grille scoop to the turbo inlet, maintaining low IATs while feeding the turbo a higher volume of smoother, denser air. The result is stronger midrange, faster turbo spool, sharper throttle response and a purposeful induction sound without the heat soak penalty.

Key Features and Benefits

  • Sealed cold air path forces cool air from the front scoop directly to the turbo for consistently low IATs.
  • Patent pending carbon fibre Venturi filter housing for laminar, efficient airflow and reduced restriction.
  • One-piece, smooth-bore carbon intake tube replaces restrictive airbox and convoluted rubber sections.
  • Pre-preg carbon fibre construction for excellent heat insulation, durability and stunning OEM-plus aesthetics.
  • Gen 2 high-flow filter in a carbon housing engineered for maximum flow and filtration performance.
  • Noticeably quicker spool, improved throttle response and enhanced induction sound on the road.
  • Designed specifically for the Audi B9 S4 and Audi B9 S5 platform for optimal fitment and performance.

The Eventuri Difference

This is not a simple cone filter with a heat shield. The Eventuri carbon fibre Venturi housing creates a controlled, aerodynamically efficient path from the filter to the inlet tube. By redesigning the complete inlet track from the front grille scoop to the turbo inlet pipe, Eventuri delivers a class-leading Audi B9 S4 S5 intake that outperforms typical open intakes, especially under real-world heat and speed.

Real-World Results You Can Feel

Tested back-to-back on the same day and same road with VBOX, this intake consistently reduces 60 to 130 mph and 100 to 200 km/h times. That improvement under high airflow shows the system’s efficiency on the road, not just on a dyno chart. If you want an Audi S4 S5 induction kit that actually lowers IATs and improves acceleration, this sealed carbon fibre intake is the upgrade to choose.
