VERUS ENGINEERING A0259A-BLU Air Oil Seperator Kit, Blue for SUBARU WRX / STI (GR / GV)

Description VERUS ENGINEERING A0259A-BLU Air Oil Seperator Kit, Blue for SUBARU WRX / STI (GR / GV)

The VERUS ENGINEERING A0259A-BLU Air Oil Separator Kit is designed to keep the intake system of the Subaru WRX and STI GR/GV platforms free from oil contamination. By removing oil from crankcase vapors before they are reintroduced into the intake, the system helps maintain effective octane levels, reducing the risk of detonation, power loss, and carbon buildup.

The unit installs in an OEM-style configuration and does not require changes to engine tuning or vehicle setup. A single AOS housing filters both the crankcase vent and intake vent locations, utilizing four coalescent filters, internal baffling, and stainless steel mesh to achieve high-efficiency oil separation. An optional coolant hook-up kit allows engine coolant to circulate through the AOS body, minimizing condensation buildup during colder operating conditions.
