I've done a bit of searching and have only found a few real performance parts at StreetKiaz and most all for Sephia/Spectra.
Does anyone know of any good upgrades for the 2001 OPtima? I guess a modded ECU would be a good start, anything to kind of boost the performance of my
2.5L V6. It seems like this 6 should be able to get more mojo to the wheels but maybe its just an inefficient tranny?
