Air Intake Hose
The hose has three functions. One is to allow a slight relative displacement of the hard pipes at both ends of the hose, which is a better way to deal with vibration and a means to compensate for thermal deformation; the other is to retrieve manufacturing errors and make two hard pipes that need to be connected. It doesn’t have to be accurate. It is meaningless to improve manufacturing accuracy and increase manufacturing costs. The use of hoses on the intake manifold takes into account these two functions; third, it is versatile, as long as it can be obtained and the length is sufficient, no need to consider Curved shape.
