VW 4-Cylinder Windage Tray

Oil pan windage tray with integrated gasket for 8v and 16v 4-cylinder motors supplied between 1975-1999 (non-06A/B): This is practically a required upgrade for any modified or aggressively driven VW. It even delivers meaningful benefits on stock vehicles. By blocking the movement of oil mist into the block, parasitic power loss is reduced. This part was supplied stock on some 2.0L 8V ABA engines.
