Installation Guide (Quick Reference)

1. Locate the existing air‑filter housing on your vehicle’s intake system.
2. Remove the old filter insert by lifting the retaining clip or screws.
3. Place the Bosch 1457433338 insert into the housing, ensuring it sits flush against the mounting surface.
4. Secure the housing cover and reattach any clips or fasteners.
5. Check for a snug seal; no gaps should be visible between the insert and housing walls.

Maintenance & Care Tips

• Regular Inspection: Check the filter every 5,000 km or as recommended by your vehicle’s service schedule.
• Cleaning Not Recommended: The paper media is designed for single use; attempting to clean can compromise filtration integrity.
• Storage Conditions: Keep unused filters in a dry, cool environment away from direct sunlight to preserve material properties.
