Why are there different car air filter shapes?

Answer 1

there are three reasons:
1) the actual task of any engineer is make things work cheap with as much crap that you have that is not being used. (aka make garbage into gold)
2.) air/fuel requirements of the engine
3.) make it look pretty in the SPACE that you have to work with

Answer 2

because they are designing cars differently now. Used to be all had a carb, and a round filter was THE shape to use for maximum efficiency ( and ease of manufacturing ). Now, though, they're fitting engines into tighter spaces, and using fuel injection, so the filter can be shaped differently because it's put into a more remote area. So it now becomes a matter of expediency and space available, rather than having the carb location dictate the design.

Answer 3

Amount of air filter life. Packaging space for the filter. Height of the engine hood clearence. Requitements of specific air flow across the Air Flow Meter. There are as many reasons as there are shapes of air filters. Here is one! Imagine your driving a new car some one flicks a lit cigarette out the window in front of your car. That smoldering Butt gets sucked up into your air filter and catches the airfilter on fire that fire melts the Air Flow Meter then starts the intake manifold on fire because it is made of plastic these days.

Answer 4

Some will tell you it's because of the air flow set up of the engine in your car. They can charge more money. Its their way of saying thanks for buying my expensive car.

Answer 5

some are bigger to filter more air for bigger motors nd some are smaller for smaller motors some are less restricted airflow many reasons

Answer 6

cause there different size motors in different size cars
