Air hoses in a car work to feed fresh, cold air to the air filter in your car’s engine. Cold air, found in areas not affected in any way by the engine’s ambient heat, travel through car air hoses to your engine’s combustion chamber. A damaged or faulty car air hose can cause a lot of problems affecting the way your vehicle performs. While car air hoses are made to last and are usually durable, cracks can often appear in them over time. Choosing a quality car air hose will help your engine to run smoothly. Above all, a great car air hose is sure to prolong the life of any engine, and promote the efficient running of any car.
