Product Details

The Dinan D401-0310 Replacement Breather Filter is engineered to provide superior engine ventilation and filtration for 1996-2001 BMW 740i models. This high-performance filter replaces the factory breather element, ensuring optimal crankcase ventilation while maintaining engine efficiency.

Key Features:

  • Multi-layered cotton construction with deep pleats maximizes airflow and filtration efficiency
  • Steel wire mesh reinforcement provides structural integrity and dent resistance
  • Enhanced filtration captures contaminants while allowing proper crankcase pressure relief
  • Direct replacement for OEM breather filter—simple installation
  • Filter sold individually

Dinan's precision-engineered breather filter maintains proper positive crankcase ventilation (PCV) system function, helping to reduce oil vapor buildup and extend engine life. The durable steel mesh core ensures the filter maintains its shape under engine bay heat and vibration.
