Buying Guide

Match to your engine and PCV system

Confirm inlet/outlet sizes and mounting options to ensure compatibility with your vehicle's PCV or fuel line routing

Prefer baffled or multi-stage filtration

Baffled designs and multiple separation stages reduce oil carryover and improve long-term crankcase ventilation performance

Check construction material and capacity

Aluminum bodies resist corrosion and 300 ml-class reservoirs balance compact fitment with practical catch capacity

Look for included hoses and fittings

Kits that supply hoses, clamps, or breather filters simplify installation and reduce the need for extra parts

Serviceability matters

Choose units with easy-to-drain reservoirs and accessible filter elements for routine maintenance
