And do cars use both or do they only require one?

    The air filter is IN the cold air intake. Some cars don't use the term, but all ENGINES require a filtered air source for combustion.

    All engines require an air filter. A cold air intake is standard on all modern vehicles

    Every car and truck comes with a perfectly good CAI from the factory. it's just plastic with a replaceable air filter instead of a shiny chrome CAI with a cleanable air filter. It's not only a waste of money but the cleanable air filter actually ruins MAF sensors when the oil on them migrates to the wires in the MAF sensor. Save your money.

    Every modern vehicle comes with a factory installed cold air intake, meaning it draws air from outside of the engine compartment. Every modern air intake system has an air filter to keep particulates from entering the intake system.

    I never could figure that logic out.  What burns in the engine is gasoline vapor which happens when the gas evaporates into gasoline smell.  So the hotter it is, the faster the gasoline boils into vapor. Having a Cold air intake keeps the gasoline liquid for longer(meaning it enters the cylinders as a liquid. and is pushed out the exhaust pipe to burn in the exhaust system, not doing work and exploding and pushing down the piston for a power stroke.  That fuel now in the exhaust pipe burns outside of the engine and produces black smoke as there is not enough oxygen in the exhaust pipe to continue with clean burning.

    .  Also in both cases you still need an air filter.  

    Cold air intake just means a scoop to catch the cold air and jam it into the motor so I am pretty sure they have an aircleaner.

    I prefer just keeping the stock air filter. Those cold air intakes don't really do anything for performance and cost way too much. They don't filter the air nearly as good as a stock air filter which is the whole point of an air filter. I've noticed people who use cold air intakes will have more carbon on the throttle plate and sometimes causes stalling.
