To ensure the high-quality operation of the internal combustion engine, the maximum purification of the air used for the combustion of the corresponding fuel is important. The penetration of dirt and dust into the purified air provokes the formation of carbon deposits on the cylinder head valves, as well as in the piston rings. As a result, the resource of the motor, as well as the power output, are reduced significantly. To solve the problem, use an air filter pipe. With high dustiness, it is irreplaceable. The hose connects the air filter with a high-raised snorkel. It protects the filter element from dust.

The functionality of the air supply hose

The FEBI BILSTEIN brand Hose, air supply cleaned air to the intake manifold. Therefore, high requirements are imposed on it. The power and resource of the motor depends on the condition of the hose. If it is not sealed, impurities penetrate into the cleaned air. They contribute to the formation of soot. As a result, when mixed with unburned fuel, the soot forms an abrasive viscous substance. The wear of the piston rings increases many times over. This has a detrimental effect on the condition of the valves and cylinder walls.
