• Durable Construction: Black plastic housing and a resistor level sensor provide a balance of corrosion resistance and proven sensing technology.
• Connector Details: Female connector with 4+4 terminal quantity simplifies electrical hookup and mirrors the original connector layout.

Who It's For

The A-Premium DEF heater is best for BMW X5 xDrive35d owners and independent shops needing a like-for-like replacement that adheres to OEM specifications and reference numbers. It is suitable for those who prefer a part that aims for direct compatibility without adaptation, and for technicians who value tested heater elements and additional intrusion protection.
