Upstream and downstream are different, not sure about variations year to year. You want Mopar or NGK replacements only though.

Try rock auto for various part numbers. Do some comparison here. The dealer will likely be overpriced.

NAPA also has an AMA discount if you have a membership. Oddly, their before sicount price was better than Autovalue and Partsource.
