The crankcase ventilation filter 7.74104 stands out thanks to its high-performance filter material and excellent fitting accuracy. Polypropylene edge provides constant strength even under high temperature conditions. The ventilation filter prevents the penetration of gases that are contaminated with engine oil from the crankcase into the intake port of the turbo-charger. The oil that is filtered out of the air is then added back to the circulating oil, thereby reducing oil consumption
