Why to replace air filters? Symptoms of clogged air filters
If you don't replace your air filter, it will get partially clogged and reduce the air intake inside your engine.

On old carbureted engines or on diesel engines, black smoke will be seen going out of the exhaust.
Regularly replacing the air filter of your car is a must and should be carried out at the above mentioned frequencies.

1- Replacing air filter on older engines
On older engines, the air filter could be changed most of the time without tools.
The air filter cover was simply held in place with steel clips which once removed, provide access to the air filter cartridge. All you have to do is insert a new air filter cartridge and put the clips back in place and that's it.
Such mountings are not much tight however, reason why on newer engines, screws have replaced the springs and clips for fixing the air filter box cover as shown further below.
