Does a airintake ADD or DECREASE MPG?

1. Dont use HTML... our site doesn't support it.

2. Don't trust the "tornado" or the fan you posted. They're both full of hype. They say they can increase your engine up to 35hp, but the most you'll get is 1 or 2 hp... and the tornado gives you about 1mpg more.... not worth the money unless your THAT CHEAP! (And if you were cheap, you wouldn't buy the tornado because it's expensive.)

3. The best way to get HP is the get your basic air filter/pipe. Given the right equipment, it's your best way to get more than 5 - even 10 - horsepower.
