Fits 2015-2020 Subaru WRX.

The Cobb Air Oil Separator (AOS) is an essential upgrade for maintaining the health and performance of your FA20DIT engine. By intercepting oil vapor and moisture from the crankcase ventilation system before it reaches the intake tract, this kit prevents carbon buildup on intake valves and reduces the risk of engine-damaging detonation caused by oil-diluted fuel. It is a proactive solution for keeping your intake manifold, intercooler, and turbocharger piping clean.

  • Protects intake valves from carbon deposits and oil fouling
  • Maintains consistent fuel octane levels by reducing blow-by
  • Durable construction with high-quality fittings and hoses
  • Designed for a precise fit within the engine bay
  • Manufacturer Part Number: 843615
