I have for sale an Airaid 353-210 intake system that I used on my SXT for a couple months before I traded it in on my RT. It is in like new condition and the blue filter element is very clean. $170 shipped.
This 353-210 will work on your R/T too, if you saved the various fittings that came with it. Or maybe you are going a different direction with this car? I'm just giving you info that maybe you didn't realize.
