The Convoluted BQL 22 Breather Hose is the core of the Nuke Performance BQL 22 system, designed to deliver maximum crankcase ventilation with minimal flow restriction.

The lightweight, flexible convoluted design allows easy routing in tight engine bays while maintaining high mechanical strength. Combined with BQL male hose ends and quick-connect adapters, it provides a full-flow solution for both recirculating and atmospheric oil catch can installations.
