The work turbochargers 4" compressor outlet adapter allows you to connect your intercooler piping to the V-band outlet on your S4E, S45E, GT47/50/55 and most other compressor housings with this flange style. Our kit is engineered with a smooth radius transition to ensure the least amount of turbulence is created during the transition. The kit includes an aluminum flange, o-ring and clamp.
