I was looking around on the Kia Soul forum and I saw that many people were installing cold air intakes and new exhaust systems for added HP.
Will either of these mods help my mpg? I don't really want to do anything to hurt the mpg...but at the same time I do enjoy kicking my horses around once in a while and as such want to upgrade the motor a bit... currently if I sit at a light and rev for the babe next to me...it sounds lame and I hit 3rd gear and it puddles out till i can get the rpms way up, and by that time the smokin hot babe has, well, smoked me...LAME!
