Overview:
Radium’s sealed catch can system does not vent to atmosphere (VTA), making it emissions and track legal. It promotes negative crankcase pressure, keeps intake components clean, and prevents oil vapor from entering the cabin. The system routes filtered crankcase vapor back into the intake for complete combustion.

Key Features:

• Increases performance by maintaining cleaner intake air

• Captures oil and fuel vapors before they contaminate intake manifold

• Helps raise fuel octane by reducing oil ingestion

• Reusable stainless steel internal baffle filter

• Anodized, corrosion-resistant construction

• Integrated dipstick for easy fluid level inspection

• Fluid capacity: 7oz (207mL)

• Can dimensions: 5" tall x 2.45" diameter
