Description

This adapter, also called a pressure control valve, comes stock on 2.0L gas VW’s with an AEG engine code.

It also fits the oil cap on the valve cover assembly of many 1.9L TDIs where it will create a second breather location for the cylinder head. This allows the engine to vent excess pressure within the cylinder head, providing increased flow of oil to the head and turbo. This is especially beneficial in those TDIs that have been modified for higher power and torque.

Fits the Following:
1998-2003 VW New Beetle 1.9 TDI & 2.0L
1999.5-2003 VW Golf 1.9 TDI & 2.0L
1999.5-2003 VW Jetta 1.9 TDI & 2.0L
