Product Description

The Arrowhead Hose Breather Oil Separator is designed for the breather engine system in selected BMW models. This component plays a vital role in directing crankcase gases away from the engine, helping to maintain clean airflow and reduce oil vapour build-up. Constructed with a flexible, corrugated design and specialised connectors, it ensures secure fitment and reliable operation under engine bay conditions.

This breather hose is compatible with specific BMW models, including the E81, E87, E90, Z4, E85, 120i, 320i, and 2.0i engines with the N46 engine code. Always check your vehicle's model, year, engine size, and engine code to confirm compatibility before purchasing.

Common symptoms of a failing breather hose include rough idling, increased oil consumption, oil leaks around the engine, engine warning lights, poor engine performance, excessive smoke from the exhaust, and a noticeable smell of oil vapour. If you notice any of these issues, the breather hose may be compromised.

Replacing the breather hose is recommended when it becomes cracked, brittle, or blocked, as this can lead to engine performance problems and increased emissions. Regular inspection and timely replacement help to prevent further engine damage and maintain optimal operation.

MiMi Auto Parts offers this Arrowhead breather hose with nationwide delivery across South Africa. Trust our expertise to help you find the right part for your BMW, and remember to always confirm your vehicle details before ordering.
