The Radium Engineering Air Oil Separator (AOS) Return Kit (MPN: 20-0351) is a specialized upgrade for the FA20 engine's crankcase ventilation system. While standard catch cans require periodic manual emptying, this return kit allows collected oil to drain back directly into the oil pan. This ensures the AOS remains maintenance-free while keeping the intake tract free of oil vapor and moisture contamination.

By preventing oil blow-by from entering the induction system, this kit helps maintain octane levels and reduces the risk of carbon buildup on the intake valves. The result is a cleaner-running engine with more consistent performance during high-load driving or track conditions.

  • Specifically engineered for the Gen 1 ZN6/ZC6 chassis
  • Integrates with Radium AOS to enable automatic oil drainage back to the pan
  • Maintains cleaner intake air for improved combustion stability
  • Includes necessary fittings and plumbing for a secure, bolt-in installation
  • Manufacturer Part Number: 20-0351
