Double thick copper sealing washer – replica of original Audi part N0138144.
Originally created for 2.7T B5 S4 engines, but it is also used to create extra space for coolant lines on K04 turbochargers.
No longer available from Audi, this washer is made by our machine shop and it is included with CTS-TR-1050, CTS-TR-1070X, CTS-TR-1070 and CTS-TR-1070X.
