Honda 17211-ZA7-000  Air Cleaner Element

The purpose of the Air Filter is to allow a constant supply of air into the engine while stopping any dust, dirt, bits of grass, or other small debris from passing through and potentially causing damage to the cylinder and piston. If the air filter is clogged, it can prevent proper air flow and cause the engine to lose power. Home users often replace their air filter during their annual tune-up. Replacing an air filter will improve the performance and prolong the life of your equipment.
