An Air Cleaner Hose is for delivering filtered air from the air cleaner to the engine's intake manifold. The air cleaner line hose's innermost layer is made of a synthetic material resistant to the effects of compressed air, oil, and other contaminants. This layer prevents air leakage and maintains the integrity of the hose. Attributes:• Inner Diameter gradually changes from 76.2mm to 101.6mm• Can withstand high pressures, abrasion, and harsh environmental conditionsApplications:An Air Cleaner Hose transfers air from the air cleaner to the engine's intake manifold, This process ensures that the engine receives a clean and regulated airflow.
