Description

The CTS Turbo double thick copper sealing washer, part number N0138144, serves as a precise replica of the original Audi component. Initially engineered for 2.7T B5 S4 engines, its utility extends to providing necessary clearance for coolant lines on K04 turbochargers. This part is no longer available directly from Audi and is manufactured by CTS Turbo's in-house machine shop. It is also supplied as part of several CTS turbocharger kits, including CTS-TR-1050, CTS-TR-1070X, CTS-TR-1070, and CTS-TR-1070X.
