    2003 3.1 different than other years?

    Hi, i have a 2003 grand prix se with the 3.1L and i cant find any aftermarket parts such as throttle body spacer, cold air intake,etc. Is there a difference in the 3.1L in 2003 compared to the 97 to 02 3.1L's because they make them for those years? Any help would be much appreciated!
