Automotive air filter will use paper filter, and rarely use the sponge filter which is why?
Paper filter effect is good, but the motorcycle on the paper filter is too small, the intake resistance is great, the impact of the intake. Scooter with paper filter, because scooter inlet from the ground is too low, the air is too dirty; cross bike inlet high from the ground, so are filter sponge. Did you find out? Cross bike in a vat generally more durable than scooter, so for motorcycle, as long as the inlet opening in the height, with a sponge filter is sufficient. The air inlet efficiency of the sponge filter element is high, the resistance is small, and the air intake noise is low. The atomization of fuel more sufficiently, so the engine more power and more fuel-efficient.
First of all, said the sponge air filter: sponge air filter with good air permeability and low cost and widely used in the motorcycle,
1, the price is low. 2, can be used to clean circulation. 3, fast speed. 4, the effect of dust without paper air filter. 5, the engine protection is low.
Re talk about the paper air filter: 1 expensive, 2 can not be used for cleaning and recycling, 3 speed slow, 4 dust better effect. 5, higher engine protection.
Speed slow car owners believe that there is a deep sense of the original, the original SUZUKI paper air filter, loaded up after the test is not aware of the normal 50-60 normal, but would like to speed up.
Here with your friends want to be modified, the pursuit of speed and fast speed, please do not choose the paper air filter (air permeability) reason has been said. The pursuit of longer engine life is not to consider the speed of the paper air filter can be selected.
Summary: the utility and cost of sponge air filter is better than that of paper air filter.
But in the car because the sponge filter can not achieve enough filtering effect, so most of the car air filter will use paper filter.
