Review on 🚀 K&N Cold Air Intake Kit for 2007-2010 Chevy/GMC Heavy Duty (Silverado 2500/3500, Sierra 2500/3500) 6.6L V8 Diesel, 57-3066 – High Performance, Increased Horsepower, 50-State Legal by Christopher Smith

I bought one of these for my gas powered Chevy pickup when I had it and didn't get more torque but got back the fuel economy that was lost lifting it up. I bought this for my new Chevy and have definitely seen the impact on the performance and mileage of my 2008 Chevy Duramax. Put it on and WOW, a noticeable difference in torque and an overall 2-3mpg improvement. Thanks to K&N for a great product and of course a million mile filter that only needs an occasional cleaning.
