I own a 2013 Chrysler 300S and was possibly looking to upgrade the air intake. K&N seems to be the most highly recommended brand I've seen through various sources. When I was on their site, after inputting my make and model, they had no cold air intake systems pop up for the 300S 5.7L V8, only for the 300C 5.7L V8. Is there an actual difference between the 300S and 300C? Or will their parts work for both models? Any other cold air intake suggestions/recommendations are appreciated.
