Catch Can Kit BMW E46 M3 Radium Engineering
Compatibility
- BMW E46 M3 (left-hand drive only)
- Not compatible with right-hand drive models
Overview
An oil catch can is an essential upgrade for performance vehicles, helping protect the engine from increased crankcase blow-by generated during aggressive driving. Excess oil vapors entering the intake system can reduce performance and contaminate intake components.
Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick.
The closed-loop system does not vent to atmosphere (VTA), making it emissions and track legal. It filters oil and contaminants from crankcase gases before routing clean air back into the engine while maintaining negative crankcase pressure for optimal performance. The closed design also prevents unwanted oil vapors from entering the cabin.
