Product Description

This Arrowhead hose breather 401905 to dipstick is an essential engine breather component, specifically designed for BMW models. It serves as a vital link in the engine's ventilation system, routing crankcase gases from the breather to the dipstick tube and helping to maintain proper engine pressure. Constructed from durable plastic with secure molded connectors, this part ensures a reliable seal and fit for consistent engine operation.

This breather hose is compatible with select BMW vehicles. To ensure a perfect fit, always confirm your model, year, engine size, and engine code before placing your order. An incorrect or poorly fitting breather hose can compromise the efficiency of your engine’s ventilation system.

Common symptoms of a failing breather hose include oil leaks near the dipstick or engine, rough idling, increased oil consumption, visible cracks in the hose, engine warning lights, or a noticeable smell of oil vapour. If you experience any of these issues, the breather hose may need attention.

Replacement is recommended when the hose shows signs of cracking, brittleness, or oil seepage, or as part of routine maintenance during engine repairs. Timely replacement helps prevent unfiltered air or oil vapours from entering the engine and ensures optimal crankcase ventilation.
