Easy drop in the box brand new Chrysler ,300C. Will see on performance and gas mpg.
Ryan, El Centro
After install the throttle lag is gone when you press the pedal it wants to go now which is great. I also have a mid muffler delete on my 2012 Charger R/T and this filter also contributes to its pure HEMI growl. I am very pleased with this air filter so far.
