Its primary function is to remove oil mist and vapors from the blow-by gases before they are recirculated back into the engine or expelled into the atmosphere. Proper functioning of the oil separator helps to maintain engine cleanliness by preventing oil buildup in intake components and reducing oil consumption. This leads to more efficient combustion and can contribute to a longer engine lifespan. Engineered by GATES, a trusted name in automotive components, the EMH946 is built to meet stringent quality standards, ensuring reliable performance and durability. Installation of this part helps in maintaining the integrity of your emission control system and overall engine health.
