The air intake breather hose pipe with OEM number 13717803842 is a vital engine breather component engineered to connect the cylinder head cover to the air filter housing on a range of BMW diesel models, helping to regulate crankcase ventilation by routing blow-by gases back into the intake system for cleaner, smoother combustion. This flexible breather pipe helps maintain balanced airflow and reduces oil vapour buildup in the intake, which supports consistent engine performance and prevents common diesel-engine issues like rough idle, accelerated carbon buildup or increased oil consumption.

Designed to replace BMW part number 13717803842 / 7803842 for a precise fit on compatible diesel engines.
✔ Supports Proper Crankcase Ventilation
Ensures blow-by gases are recirculated into the air intake system, helping reduce emissions and prevent pressure build-up in the engine crankcase.
✔ Prevents Oil Vapour & Carbon Buildup
A functioning breather hose reduces oil vapour entering the intake, which helps minimise carbon deposits on intake valves and sensor elements.
✔ Durable Aftermarket Construction
Made from flexible, heat-resistant materials designed to withstand engine bay temperatures and repeated flexing without cracking or splitting.
✔ Wide Vehicle Coverage
Compatible with various BMW models including X1, X3, X4, X5 and X6 diesel models (as well as equivalents on 1/3/5/7 Series with N47 and N57 engines) — check compatibility with your vehicle before ordering.
Frequently Asked Questions
Q: What does an air intake breather hose pipe do?
The breather hose pipe redirects crankcase blow-by gases back into the intake system, allowing these gases to be burned during combustion rather than venting them into the atmosphere, improving engine efficiency and emissions control.
Q: How do I know if this breather hose needs replacing?
Signs of a failing breather hose include cracked or split hose material, oil residue around the connections, rough idle, increased smoke or a check engine light for crankcase ventilation issues. Any air leaks here can affect engine air/fuel balance.
Q: Is this part compatible with my BMW X-Series?
This breather hose fits many BMW X1, X3, X4, X5 and X6 diesel models equipped with N47 or N57 engines — always verify using your OEM part number or vehicle details before purchasing.
Q: Can I install this myself?
Yes — this hose is usually a direct swap with the old unit. If you’re unfamiliar with engine bay components, professional installation is recommended.
Q: Will replacing this hose improve performance?
Replacing a worn or cracked breather hose helps maintain proper crankcase ventilation, which can stabilise idle, reduce oil vapour buildup and help the engine breathe more efficiently under load.
