i checked VIN number and it has a CA on it, does that necessarily mean its a cali spec?

 

Probably, but the easiest way to tell is to look at your front bank of cylinders and there is either 4 or 2 plug connectors between the cylinder bank and the radiator. (those are for the O2 sensors I believe) (4 is cali specs).

 

I'm not going to say it, hint it begins with the letter "S".
