I'm considering installing a K&N 63 Series Aircharger Kit on my 2006 Chrysler 300C to increase horsepower. Per K&N will gain 21hp at the rear wheels. Would like any input regarding this product before I purchase said item. Thank you.

 

K&N makes great products. A buddy of mine has the complete CAI kit on his chevy and he says he can definitly feel the difference.
