The crankcase ventilation filter 7.74104 distinguishes itself through its highly-efficient filter material and excellent accuracy of fit. The polypropylene edge ensures permanent stability, even under high temperature conditions. The ventilation filter prevents that unfiltered blow-by gases, contaminated with engine oil, will be directed from the crankcase into the intake passage of the turbocharger. The oil filtered out of the air is then added back into the oil circulation so that the oil consumption and total emissions of the engine are efficiently reduced.
