Review on 🚀 K&N Cold Air Intake Kit for 2007-2008 Ford F150, 4.6L V8: High Performance & 50-State Legal: Boost Horsepower with 57-2574 by Jason Dahlkemper

This is a great kit that will not only allow your F150 to breathe better but also perform better. Having just installed this kit it's too early to tell how much of an impact it will have on fuel economy but we'll see. I believe anything that helps make an engine more efficient can only add more horsepower and fuel economy per gallon. Installation was easy, and even a person not very knowledgeable about mechanics could disassemble it in 1-2 hours. They'll also make your truck sound great, but be careful - don't pedal because it sounds so great, or you'll soon be getting less mpg than you did before you installed it. My kit was missing a bolt on the saddle mount that supports the pipe but luckily I had the exact same one in my parts cart so this wasn't a deal breaker and doesn't justify taking off those 5 stars. Valuation. If you're on the fence, as I have been for a long time, this isn't meant to be. Yes they are a bit pricey but in the long run you will be glad you got these.
