RADIUM Engineering 20-0378-FL Crankcase Catch Can Kit for Ford Fiesta ST with Fluid Lock

The RADIUM Engineering 20-0378-FL is a crankcase catch can kit specifically designed for 2014-2019 Ford Fiesta ST models. This complete bolt-in system protects your engine from elevated levels of crankcase blow-by accumulated during high-performance driving by preventing oil and sludge from contaminating the intake system.

Key Features:

• Anodized aluminum catch can with integrated condenser and dipstick for easy fluid level inspection
• 7 fluid ounce capacity with 4.9-inch height and 2.45-inch diameter
• Patent-pending Fluid Lock technology that prevents contaminants from exiting if the can fills up
• Machined from solid 6061 aluminum with O-ring sealed construction for pressurized applications
• Dual internal stainless steel air/oil separators (inlet and outlet) for advanced filtration
• Fiesta ST-specific anodized aluminum mounting bracket that secures to ECU mounting studs
• 10AN ORB (7/8"-14) main inlet and outlet ports with included fittings and hose ends
• Complete hardware kit with stainless steel mounting components and PCV hose
• Fits under OEM engine cover with no modifications required
• Closed-loop system design - does not vent to atmosphere (emissions and track legal)

Installation and Benefits:

This catch can runs inline with the crankcase vent port. During high-load conditions (wide open throttle), the crankcase experiences high flow that would normally lead to oil accumulation in the air filter intake pipe and intercooler, reducing thermal efficiency and performance. The RADIUM system intercepts these contaminants before they enter the intake system, raising effective octane levels and maintaining optimal engine performance. Installation requires no cutting, drilling, or permanent modifications to the vehicle.

For maximum engine protection, RADIUM Engineering recommends pairing this crankcase kit with the separate PCV catch can kit (sold separately) for a complete dual catch can system that addresses both engine breather circuits.
