We own two Impalas. Both are 2013 model years. The only difference are the body colors. I have a K&N air filter in mine and she has another replacement brand air filter. My car has more horsepower and less lag upon accelerating and passing vehicles on the highway. Hands down, I'll be a K&N customer for life.

Website easy to navigate and locate the part I was looking for. After ordering, it was delivered on the date promised. Easy install. Still monitoring the results, but initially look like they will equal or exceed advertised numbers.
