Good night, I have a doubt about the camshaft for my Kia, model: Spectra II 1.6L LS, year: 2002. The VIN of my car is KNAFB227225185766 and the damaged part has printed the following code K30E K1-2, and the number 421. I need to buy the camshaft identified by "0K30E12420A CAMSHAFT ASSY-INT" but I don't understand what does the following codes mean: K1-1 K2-2 K3-2 K4-1 K5-2 K16-2 (none of which is the one my car originally had), and what is the difference between one camshaft with a K code (for example K1-1) or other (for example K4-1). If you'd please help me to understand that so I can buy the appropriate camshaft for my car. Thanks in advance, Argenis Blanco.
