Why is a dry element air filter pleated
To increase the surface area
Its easier to manufacture
It improves the look
It cools the air down
Apart from removing particles from the air the air cleaner also
Increases the oxygen
Quietens the air intake
stops smoke in the exhaust
Pressurises the air
Two other types of air cleaner can be known as a:
oil shower and cycle home
oil bath and spinner
oil bath and cyclone
oily cyclone and wet bath
Intake manifolds are tubes connected to the inlet ports of an engine to guide in:
