Review on 🚀 K&N Cold Air Intake Kit: Unleash High Performance! Boost Horsepower with the 50-State Legal 2007-2009 Dodge Ram (2500, 3500) 6.7L L6 Diesel,57-1557 Upgrade by Daniel Bulkley

Would suggest a mechanic for installation if DIY isn't your thing. The installation guide for it isn't very good and the parts package doesn't match what I needed to have in the installation guide. I had two full tanks. So far no improvement in mileage and I don't see any increase in performance either. The only difference is that the engine sound is slightly different (turbo). That's a lot of money to spend on zero upgrades.
