Mann Filter cartridge oil filter HU 6004 x for BMW 328d/535d/X3 xDrive28d (2014–2018) — OE media, high dirt-holding capacity

The MANN-FILTER HU 6004 x is a direct-fit cartridge oil filter element engineered to protect diesel BMW engines by capturing contaminants while maintaining stable oil flow during cold starts and heavy use.

Modern European diesel engines rely on high-performance cartridge filters to trap particles, protect precision components, and hold oil inside the housing for quicker lubrication at startup. The HU 6004 x cartridge from MANN-FILTER is designed to match the filtration fineness and physical fit required by many BMW applications, offering OE-quality media, durable end caps, and flexible O-rings so the filter performs reliably through long service intervals.

How does this filter safeguard my BMW engine?

The HU 6004 x captures contaminants and soot from diesel oil using a filter media formulated for high dirt-holding capacity. By keeping particles out of bearings, turbochargers, and injectors, it helps reduce abrasive wear and supports consistent oil pressure.

• High-efficiency media tailored for European diesel engines
• Stable performance under thermal and mechanical stress
• Durable end caps that maintain a tight seal during service

Will it fit my vehicle and how easy is installation?

This cartridge is compatible with specified BMW models (328d, 328d xDrive, 535d, 535d xDrive, and X3 xDrive28d from model years listed) that use a replaceable cartridge element. Because it replaces only the element and not the housing, installation is straightforward when following the vehicle manufacturer’s service instructions.

• Direct replacement for the HU 6004 x specification in listed BMWs
• Uses the existing filter housing—no housing change required
• OEM-style O-rings included for a secure seal during reassembly

What materials and features ensure long-lasting filtration?

MANN-FILTER designs its cartridge elements with media that resists collapse and degradation even under high temperatures and contamination loads. The result is sustained filtration efficiency throughout the service interval, with end caps and O-rings engineered to prevent bypass and leakage.

• Robust filter media with high dirt-holding capacity
• Precision-molded end caps for consistent sealing
• Flexible, oil-resistant O-rings to maintain long-term integrity

How does this filter help during cold starts and heavy driving?

Cartridge designs retain oil in the module, which shortens the time required to deliver oil pressure after a cold start. That stored oil, combined with effective particle capture, reduces initial friction and helps protect components during stop-and-go or towing conditions.

• Oil retention in the cartridge for faster lubrication at startup
• Consistent filtration even under higher contamination loads
• Maintains oil flow characteristics specified for the vehicle

Who is this product for? The MANN-FILTER HU 6004 x cartridge is intended for owners, technicians, and fleet managers who service compatible BMW diesel models and want a high-quality, OE-grade replacement element. It’s ideal for drivers who require reliable filtration across varied driving conditions—city commutes, long highway runs, or heavy-load use—without replacing the entire filter housing. For correct fitment, confirm your vehicle model year and OEM part number before purchase.
