Description
The Radium Engineering Universal Catch Can Kit – 6AN (20-1806-FL) is a complete high-performance solution designed to control oil contamination from your engine’s crankcase ventilation system. Ideal for universal and custom applications, this all-inclusive kit provides everything needed for a professional installation when a direct-fit catch can kit is unavailable.
At the center of the system is Radium Engineering’s patented Fluid Lock® Catch Can technology, engineered to prevent overfilled catch cans from returning trapped contaminants back into the intake system. This advanced design helps maintain proper crankcase ventilation while protecting engines from oil ingestion and carbon buildup.
Constructed from CNC-machined 6061 aluminum and designed for both naturally aspirated and forced induction applications, this catch can kit delivers race-proven reliability for street, track, and competition vehicles.
