I have a 2005 Kia spectra5 Automatic. I dont know much about new cars, I also need advice and knowledge from the wise. I want to make my kia really fast but I also want it to pass the smog check. Is there anything that I can do to drastically improve the performance without having it fail the smog test? If there isnt a way then Ill just leave kia the way it is and work on my 1972 Chevy Nova.
Any information is helpful, thanks
