The air oil separator is an essential component in modern internal combustion engines, particularly in turbocharged and direct-injection applications, where it functions to remove entrained oil mist from crankcase ventilation gases before they are recirculated into the intake system, thereby preventing carbon buildup on intake valves and combustion chamber surfaces. Sakes Auto Parts, founded in April 2016 by several powerful regional dealer representatives in Shanghai’s Anting Town, was established to satisfy the demand for transformation and upgrading within the automotive aftermarket, and our close-interest community structure enables us to apply advanced engineering principles to the design and manufacturing of air oil separator solutions that meet the exacting demands of modern engine architectures. Through our unified management across different administrative areas and strategic capital pooling, we ensure that every air oil separator we supply under the SAKES brand is engineered with precisely calibrated internal passages, baffles, and coalescing media that effectively capture oil droplets while minimizing restriction to crankcase ventilation flow, thereby maintaining proper crankcase pressure regulation. Our deep expertise in Volkswagen and Audi platforms has given us unique insights into the specific air oil separator requirements of these engines, where integrated PCV systems with advanced separation technology are critical to preventing the intake valve deposits that can lead to reduced performance, rough idle, and premature engine wear in direct-injection engines. By integrating research, development, production, sales, and service under one unified structure, we deliver air oil separator solutions that help professional technicians restore proper crankcase ventilation function, protect intake systems from harmful oil contamination, and provide end consumers with the reliability and performance that discerning vehicle owners demand.
