performance , strange car If you keep your foot out of throttle I'm able to achieve as high as 36 mpg. (highway), but it's really hard to maintain the car REALLY wants to go. normal driving it gets about 24mpg. very torquey engine . Car manangement will not even except k&n filter change without the check engine light coming one. so EVERYTHING except sterio is factory . Had Highperf.parts and went back to orig. parts.
