RADIUM Engineering 20-0373-FL Dual Catch Can Kit for BMW N54 Engine with Fluid Lock

The RADIUM Engineering 20-0373-FL is a comprehensive dual catch can system specifically designed for BMW N54 turbocharged engines found in the 135i, 335i, and 535i models. This premium oil catch can kit helps prevent carbon buildup on intake valves by capturing oil vapor and blow-by gases before they can contaminate the intake system, which is critical for maintaining performance and longevity in direct-injection engines.

Key Features:

• Dual catch can configuration captures crankcase vapors from both PCV and CCV systems
• Integrated Fluid Lock technology prevents captured oil from being drawn back into the intake under high vacuum conditions
• Laser-cut steel mounting bracket for secure, vibration-resistant installation
• Application-specific design ensures proper fitment for N54-equipped BMW vehicles
• Dipstick-style drain valves allow easy monitoring and servicing without removing cans
• Includes all necessary hoses, fittings, and hardware for complete installation
• Billet aluminum construction with black anodized finish for durability and corrosion resistance

This catch can system is essential for enthusiasts running higher boost levels or track-driven vehicles where increased blow-by is more prevalent. The Fluid Lock feature differentiates this kit from basic catch cans by using internal check valves that prevent collected fluids from being siphoned back into the engine during deceleration or high-vacuum situations. Regular maintenance involves draining the collected oil every 1,000-3,000 miles depending on driving conditions.
