300ZX models use oil pressure to adjust the Intake Valve timing. This genuine, original equipment (OEM) o-ring seals the Variable Timing Control (VTC) cover to the VTC gear (intake camshaft sprocket). These should be changed each time the timing belt is replaced in order to prevent failure. Sold individually, 1 required per intake cam (2 per car).
