Do all cold-air intakes for cars pretty much have the same power?? U just pay more for the brand name?

Answer 1

That is a good question. Life experience has taught me:
1. There is no real correlation between performance and price. Obviously, better for cheaper is best.
2. Everyone says his product is superior to his competitors.
3. Check to see if anyone has done an impartial comparison test on the product of interest.
4. See what other people have to say about the product and critique whether or not you even need it. Disagreeable but knowledgeable people are best for this.

That said, cold air intakes can make a perceptible difference in engine power. If you think of an engine as an air pump, anything that aids the smooth, unrestricted flow of larger amounts of cool air into the engine will help make more power. Unless you absolutely know one product is superior to another, buy on the less expensive side of the scale.

Answer 2

You'll get about 6 more horsepower at the wheels with a K&N Typhoon type intake, or at least that what they claim. You'll also get better throttle responce and perhaps a slight inprovment in fuel economy if you don't put your foot in it. The only cons I can see is if you live in California they're not CARB approved, hence they're not street legal. You'll have to remove it and reinstall the stock system everytime you get a state required smog check. You might try installing the K&N reusable air filter that designed to fit in the factory setup. They flow quite a bit better than the stock air filter too.

Answer 3

Any increase in HP should be a direct result of the volume of air that enters the intake. Size would therefore be a factor. Also, the intake should face the front of the car as to increase any "RAM" effect.
