CTS Turbo High-Flow Turbo Inlet Pipe – S4/S5/SQ5


Add to wishlist Add to compare


CTS Turbo is proud to announce our high flow turbo inlet for B9 Audi S4/S5/SQ5

The biggest issue with the restrictive factory inlet is apparent when you start to increase the power. Our engineers designed the turbo inlet to be as large as possible; yet still fit perfectly. This was accomplished using the latest in 3D scanning and rapid prototyping technology.

The larger inlet will provide increased flow to the turbo and make sure the engine has all the air that it needs to operate at maximum capacity!


  • High flow cast aluminum turbo inlet pipe
  • Precision machined fitment for the factory turbo
  • Factory-style PCV connections
  • Developed, tested and machined in-house
  • Includes new o-ring and allen head bolts for easy install
