A cheap way of adding horsepower, though not as much as ricers say they make. Usually
add 5-8 on a four pot, 10-15 for a six and 15-30 for an 8. (K&N)
People often install them because they are a much cheaper (however less effective) alternative to turbocharging or supercharging. (Can also accompany a
turbo and/ or a supercharger)

I can't afford to
turbo my
car so I got a cold air intake
That GTP is nice it has a supercharger stock and the owner added a cold air intake
