i heard people add a thing called air-intake to make the car have better performance,whats the really difference?? how much power will i gain,my car currently have 1800Lis it only the sound differences?? do i need a larger muffler?
its making the air intake cooler or less restrictive so more air or denser air into the cylinders, more air more fuel more power, also a better exhaust system that allows better flow will improve the power a little bit as the motor is using less effort the push the gas out of the cylinders, i cant say how much more power you would get but both of these will improve you power and economy.
It is more than a sound difference, but it will not make a huge difference in performance. The cold air intake will permit less restricted air into the engine. However, depending on your car model, engine and other factors, you will likely see only between a 5-15 horsepower increase. If you change your exhaust system to one with less restricted air flow, you may see a similar increase. I am not sure it is worth the money for only 5, 10, or 15 HP. Good luck.
