Description
The Radium Engineering Competition Catch Can – XL (20-1771) is designed for high-performance engines that require maximum crankcase ventilation and superior oil vapor control. Featuring an extra-large 1-quart capacity, this catch can meets the requirements of many racing organizations including SCCA, NASA, and Formula Drift, making it ideal for serious motorsports and extreme-performance builds.
Engineered for versatility, the Competition Catch Can can be configured for either Vent to Atmosphere (VTA) or Vent to Engine (VTE) operation, allowing seamless integration into a wide range of PCV and crankcase ventilation systems.
Constructed from CNC-machined billet aluminum with a durable anodized finish, this fully serviceable catch can features an advanced dual-stage vapor separation system that efficiently traps oil vapor and contaminants while maintaining unrestricted airflow for high-output engines.
