Performance Gains / Why It’s Needed

Stock Audi S4/S5 intakes restrict flow and heat quickly. Eventuri’s system reduces restriction, maintains laminar airflow, and keeps intake temperatures lower. Road testing shows up to 0.5-second reduction in 60-130mph acceleration and noticeable gains in throttle response, especially under spirited driving.

What’s Included in the Kit

• Prepreg carbon fibre Venturi filter housing
  
  

• Solid carbon intake tube
  
  

• Gen-2 Eventuri filter
  
  

• CNC machined breather components
  
  

• Ducting and mounting hardware
  
  

Warranty & Guarantee

• Manufacturer-backed warranty against defects
  
  

• Returns accepted on unused items in original packaging
  

This intake is a top Audi B9 S4/S5 performance upgrade, ideal for airflow optimization, turbo efficiency, and reducing heat soak. Pair with Eventuri Turbo Inlets or other Audi B9 performance parts for full upgrade potential.

FAQs

Q1: Will this work with the stock turbo?
Yes, designed to fit stock turbos and improve airflow efficiency.
