what type of parts are you looking for? ford owned kia but let it go it's own way. SOHC use ford and mazda parts, DOHC are a little different. on sensors some aftermarket don't work that well. some aftermarket 02 sensors don't work at all and will code. some of the guys here toyota diff's with some mods
