This FEBI BILSTEIN crankcase ventilation hose (part code 49799) is engineered to meet the specific requirements of your vehicle's emission control system.

A damaged or clogged hose can lead to increased oil consumption, sludge buildup, and potential engine damage over time. This high-quality hose from FEBI BILSTEIN ensures a reliable and durable solution for your vehicle. Crafted from durable materials, this hose is built to withstand the demanding conditions under the hood, including exposure to heat and oil.
