Using a clean air filter helps improve fuel efficiency, maintain engine power and protect key components such as pistons, cylinders and valves from dust damage. It also supports smoother throttle response and reduces engine strain. Regular replacement is important because clogged filters can restrict airflow, causing weak performance and higher fuel consumption over time, especially in city driving conditions. Return and warranty are subject to proper installation and normal usage conditions. Damage caused by incorrect fitting, water intake or overdue replacement will not be covered. Always inspect the air filter during each service interval and replace when dirty to maintain optimal engine health.
