I've have added the sma cold air intake, air raid throttle body spacer and the sma exhaust. I test drove a std h3 and an h3 that has these add ons at the dealer before i bought my h3. They do make a difference. I've got over 5600 miles since sept 12th. back and forth to work 35 miles one way country some city and express way driving. I'm getting 18.6 to 19.5 mpg. No whistle noise, deffinately louder. I'm running a slate blue, luxury pck, chrome pck, chrome step tubes and chrome rims.
