Review on ๐Ÿ”ฅ K&N Cold Air Intake Kit: Boost Horsepower for 2011-2013 Chevy/GMC Heavy Duty Models (Silverado 2500 HD, Silverado 3500 HD, Sierra 2500 HD, Sierra 3500 HD) by Tim Rushing

Great cold air intake!

Disconnecting the stock sensors took longer than installing a K&N filter. I installed this 77 series inlet on my 2013 2500HD with 6.0 Vortec. It was the perfect match! The MPG monitor immediately started to increase during the first mile I tested. The power is amazing and the sound is pretty obnoxious when you open the throttle. A great product that already shows improvements in performance after the first few kilometers of installation. I recommend this to anyone looking for better fuel economy and performance. Thank you K&N!
