Engineered to even filter minute particles of air taken in, ensuring sufficient air supply and
engine performance.A clean air filter also equates to better gas mileage, which means more money in
one’s pocket. The amount of money laid out to purchase a new air filter is well worth
it and pays for itself several times over in gas savings.
All air filters are made of a thin material, just like dust masks. These are typically paper or cloth,
although foam filters exist as well. Older cars that have carburetors typically take a circular air filter,
whereas fuel-injected vehicles generally
use flat rectangular air filters.
The air filter is considered part of the fuel supply system. Fuel
(either gasoline or diesel) is what a vehicle’s engine runs on, and getting the fuel from the
tank to the engine is a complex process. The fuel system consists of the gas tank, carburetor
or fuel injector, intake manifold, throttle body, as well as various pumps, filters (not just
the air filter but also the fuel filter), gaskets, and other parts. The intake of air to the engine
is mixed with the gasoline in a specific ratio to burn most efficiently.
