"I've already noticed an increase in power in my car. I've also noticed that it adds a bit of a lower growl to the engine. I haven't had it long enough to see a difference in gas mileage, but from what I've read, that should be better, as well. Easy Install, Fast Shipping, great product!" —Brad R from Acworth, GA bought an Injen RD Series Cold Air Intake for a 2003 Toyota Matrix.
