Crankcase Breather Hoses & PCV Tubes
Maintain proper engine pressure and prevent vacuum leaks. Over time, heat causes plastic breather hoses and PCV (Positive Crankcase Ventilation) tubes to become brittle and crack. Replacing worn hoses restores smooth idling, reduces oil consumption, and eliminates "Check Engine" lights caused by lean fuel mixtures.
- PCV System Hoses: Critical for venting harmful crankcase gases back into the intake for combustion.
- Oil Separator Lines: High-quality tubes designed to transport oil mist safely without clogging.
- Heat-Resistant Materials: Made from reinforced rubber or high-grade PA12 plastic to withstand intense engine heat.
