I have used K&N products for a long time in cars, trucks and motorcycles. I recently installed the K&N 57 Series in my 2013 2500 Silverado Duramax. Very noticeable increase in power and response. I've only run one tank of fuel so far but it appears mileage has increased too. The appearance is pretty plain when you install the heat shield but it is good to do because of the turbo heat. My only negative is the salty price.
