The 1992 Camaro features a factory setting with a ram air built into it. This is the cold air intake.
Horsepower can be increased in a Toyota Corolla by doing bolt-on additions. Connecting a cold air intake system and full exhaust system will increase the power of an engine by approximately 8 percent.
K&N states 11.83 hp gain @ 4248 rpm

A cold air intake will increase your horse power
Cold air intake is better because it's denser.
You will not damage your engine if you remove its cold air intake. The cold air intake system is merely added to increase engine efficiency and performance.
A cold air intake is an aftermarket part used to help open air flow to the engine. The cold air intake sucks up cold air from underneath the car and is attached to your intake manifold. So it is a pipe going from somewhere close to the bottom of the engine compartment leading to your intake manifold.
