K&N 33-2475 Air Filter Product Reviews

Friday, March 3, 2017 - Part 33-2475
I have two Chevy Impala's with the v6 engines. One in a 2014 2lt and one in a 2016 limited. Both have experienced increased horsepower, performance, and yes, gas mileage. I highly recommend these filters to anyone.

This is an excellent filter and this is why every time I get a different vehicle, I get a new K&N air filter.
