Technical Specifications

Installation Guide

1. Remove the old filter: Loosen the retaining ring or clamp and carefully lift the filter out of the engine bay.
2. Inspect the gasket surface: Ensure no debris or oil residue remains on the mounting flange.
3. Place the new gasket: Position the factory‑provided gasket onto the flange, aligning it with the mounting holes.
4. Insert the filter: Slide the HU 721/4 X into place until fully seated. The gasket will compress to create a tight seal.
5. Tighten the retaining ring or clamp: Follow the manufacturer’s torque specification (typically 10–12 Nm) for optimal sealing.
6. Check for leaks: After engine start, inspect the filter area for any signs of oil seepage.

Performance Benefits

• Engine Protection: By filtering out contaminants, the HU 721/4 X reduces wear on bearings and seals, prolonging engine life.
• Fuel Efficiency: Lower pressure drop maintains optimal oil flow, which can contribute to marginal fuel savings.
• Reduced Maintenance: The gasket set eliminates the need for additional sealing compounds, simplifying routine service.
• Consistent Oil Quality: Maintains oil viscosity and cleanliness over longer intervals, supporting extended oil change schedules.

Compatibility Overview

The HU 721/4 X is engineered to fit a broad spectrum of passenger cars. While it is widely used in various BMW models (including the 3‑Series, 5‑Series, and X3), its dimensions and sealing design make it suitable for many other manufacturers that require a 64 mm outer diameter filter.

For a definitive fitment list, consult the vehicle’s service manual or the manufacturer’s part number cross‑reference guide.

Quality Assurance

• Manufacturing Standards: Produced in a controlled environment with ISO 9001 certification.
• Testing Protocols: Each filter undergoes pressure drop, flow rate, and durability tests to ensure compliance with OEM specifications.
• Warranty: While the product itself is not covered by a warranty, it meets all original equipment performance criteria.

Maintenance Tips

1. Regular Inspection: Check the filter housing for cracks or deformation before each oil change.
2. Use Recommended Oil: Pair the filter with the manufacturer’s recommended engine oil to maximize protection.
3. Avoid Over‑tightening: Excessive torque can damage the gasket; adhere strictly to specified values.
