• Durable Construction: Made from high‑quality synthetic fibers and reinforced with a protective outer shell to resist abrasion, moisture, and temperature extremes typical of road environments.
• OEM Compatibility: Designed to match the exact dimensions and mounting specifications of the original air filter for a broad range of passenger cars. This guarantees a seamless fit and reliable sealing.
• Easy Installation: The filter features a simple, tool‑free installation process. It snaps into place with secure retention clips, ensuring a tight seal against dust ingress.
• Long Service Life: Engineered to maintain filtration performance over extended mileage ranges, reducing the need for frequent replacements and lowering maintenance costs.

Technical Specifications

Installation Guide

1. Prepare the Vehicle: Park on a level surface, engage the parking brake, and allow the engine to cool. Open the hood and locate the existing air filter housing.
2. Remove Old Filter: Release any retaining clips or fasteners securing the old filter. Carefully lift the filter out of its compartment, noting the orientation for correct placement of the new unit.
3. Inspect Housing: Check the filter box for debris or damage. Clean if necessary to ensure a proper seal with the new filter.
4. Insert New Filter: Align the filter’s mounting edges with the housing, then slide it in until fully seated. Ensure that the filter sits flush against the housing walls.
5. Secure Retention Clips: Reattach any clips or fasteners to lock the filter in place. Verify that all fasteners are snug but not over‑tightened.
6. Close Hood and Test: Replace the hood latch, start the engine, and listen for any unusual airflow noises. Check for leaks around the filter housing; a properly installed filter should produce no hissing or rattling sounds.

Maintenance Tips

• Inspect the air filter at every major service interval or when driving in dusty conditions to ensure optimal performance.
• Avoid forcing the engine into high‑RPM operation for extended periods, as this can accelerate filter contamination.
• If you notice a significant drop in engine power or increased fuel consumption, consider replacing the filter sooner than scheduled.
