4. Principis de funcionament
The aFe POWER D.A.S. PLUS Induction System is designed to optimize engine performance by improving the efficiency of air intake. It achieves this through:
- Flux d'aire millorat: The CAD-designed intake tube provides a smoother, less restrictive path for air to enter the engine compared to the factory setup.
- Filtració superior: The Pro DRY S filter is a high-flow, oil-free synthetic media filter designed to capture contaminants effectively while allowing maximum airflow. This results in cleaner air reaching the engine and improved combustion.
- So optimitzat: While retaining the factory airbox, the system subtly enhances the induction sound, providing a more aggressive tone under acceleration without being overly intrusive.
These combined elements contribute to increased horsepower, torque, and improved throttle response, enhancing the overall driving experience.
5. Manteniment
Regular maintenance of your aFe POWER Pro DRY S filter is crucial for maintaining optimal performance and extending the life of your induction system. The Pro DRY S filter is a "no oil" filter, simplifying the cleaning process.
Filter Cleaning Procedure:
- Elimina el filtre: Carefully remove the Pro DRY S air filter from the airbox.
- Neteja el filtre: Use a soft brush or compressed air (from the clean side out) to remove loose dirt and debris. For a deeper clean, use a specialized aFe POWER filter cleaner designed for dry filters. Follow the cleaner's instructions for application and rinsing.
- Filtre sec: Deixeu que el filtre s'assequi completament a l'aire abans de tornar-lo a instal·lar. Do not use compressed air or heat to dry the filter, as this can damage the filter media.
- Reinstal·la el filtre: Once completely dry, reinstall the Pro DRY S filter into the airbox, ensuring it is properly seated and sealed.
Interval de neteja recomanat: Inspect your filter every 10,000-15,000 miles or more frequently in dusty environments. Clean as needed.
