Product Description

The Radium Engineering 20-1771 Competition Catch Can XL is a high-capacity oil separator engineered for demanding motorsport and high-horsepower applications. Its 1-quart capacity satisfies the minimum catch can volume requirements of many racing organizations while effectively separating oil and contaminants from crankcase vapors before they can enter the intake system.

Constructed from CNC-machined billet aluminum, the catch can features dual-stage internal condensing media, dual 10AN ORB inlet ports, and an integrated 4AN ORB drain port for optional remote draining. The included top plate allows quick conversion between Vent-to-Atmosphere (VTA) and Vent-to-Engine (VTE) configurations, while the fully serviceable design, integrated dipstick, and adjustable mounting bracket make installation and maintenance straightforward for custom performance builds.
