I just purchased the 2013 and noticed that very few accessories are out there yet. www.autoanything.com is a good place to look. I do know that the K&N filters are the same stock number for both 12 and 13's. Still waiting for the cold-air intake to come out for the 13's V-6.

 

This is one of the biggest challenges we face as we try to get the new model year products loaded as quickly as we can. We rely on the manufacturers for this and some are faster than others. Most of the time it just rolls up (unless it is a complete redesign) but as you have mentioned, they make subtle changes that have to be worked out.

 

I also just bought a 2013 R/T. from what i can tell , there are very little differences between the 12, and 13 models.

 

Congrats and welcome!!
