Radium Engineering Catch Can Kit

Part #: 20-0073-FL

Overview

The Radium Engineering Catch Can Kit is a high-quality, performance-oriented oil catch can system designed specifically for the 1998-2006 BMW 3-Series E46. This kit helps protect your engine by capturing crankcase blow-by vapors before they can contaminate your intake system, ensuring your vehicle maintains optimal performance and reliability. Crafted for enthusiasts who demand durability and efficiency, this catch can system is an essential upgrade for high-performance driving, track days, or spirited street use. It promotes cleaner combustion, reduces oil saturation in the intake, and helps maintain engine health over time. Designed with a focus on emissions compliance and track legality, Radium’s closed-loop system does not vent to atmosphere (VTA). Instead, it routes filtered, clean air back into the engine, supporting negative crankcase pressure and reducing harmful emissions. This makes it suitable for both street and track applications, providing peace of mind and compliance with emissions standards.
