product key technologies

- Installation: Direct bolt-on replacement. No modifications required. Ensure all clamps and latches are securely fastened to maintain an airtight seal.
- Maintenance: Periodically inspect the dust bowl and pre-cleaner cartridges. Under normal conditions, replace the filter element every 20,000 km. In dusty or high-contamination environments, reduce the interval to 15,000 km.
- Warning: Do not operate the vehicle with a damaged housing or improperly sealed filter assembly. Air bypass can introduce abrasive dust into the engine intake, causing accelerated wear.
