CTS Turbo 4" Turbo Inlet Pipe for 8Y Audi RS3

CTS Turbo is proud to announce our Cast Aluminum 4" turbo inlet for 8Y Audi RS3. This is the first ever 4" inlet compatible with the updated 8Y RS3 models, with an additional PCV connection on the factory turbo inlet pipe. 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. This results in a 78% increase in volume over the stock turbo inlet. The larger inlet will provide increased flow to the turbo and make sure your 2.5T has all the air that it needs to operate at maximum capacity! This is one of the largest inlet pipes on the market at the perfect price point.

PLEASE NOTE A 4" INTAKE PIPE IS REQUIRED. THE OEM INTAKE PIPE IS NOT COMPATIBLE WITH THIS KIT.
