Do cars use cold air intakes and air filters or just require one?

    Cold air is not legal in all states & yes, theirs still a filter. You want a filter to clean the air going into the motor.

    All internal combustion engines run best when the incoming air is clean/filtered.

    The incoming air is more dense if it is cold and the engine can produce more power when the air is more dense.

    Factory stock air filters are usually the best possible design for an engine and are tuned for it.  Most CAI ( cold air intake ) systems either won't provide any additional power over stock or could possibly even hinder performance and/or the oil from the washable air filter can damage the sensitive film on the mass air flow sensor.

    All vehicles come with a perfectly fine cold air intake.

    Cleanable air filters have oil on them that migrates to the MAF sensor wires and ruins the MAF sensor.

    They're not required they're used because studies are said to show that using cold air improves performance and fuel mileage.

    Yes, you need clean air going into the engine to ignite the fuel mix, no air no run. So yes they need and use the clean air.

    An air filter is necessary because you don't know where that sh*t's been.

    All modern fuel injected vehicles come from the factory with a tuned cold air intake and an air filter. Replacing the factory cold air intake with an aftermarket cold air intake almost always results in LESS performance. See this post on cold air intakes

    Even with "cold air" a filter is needed to keep airborne "crap" out of your engine. Of course if you want to ruin your engine you can skip the filter.
