Depends on what you want
HP increase is quite noticeable unfortunately so is the decrease in mpg.I have this intake with a AFE throttle body spacer in my '14 F350 and it's great as long as you don't mind lowering your fuel economy,but it does make you want to keep a little extra weight on the skinny pedal.
Bad part they knew about
I installed this cold air system and the first time I drove it, It would had trouble pulling any boost. I thought during the install that the hose from the turbo to the intake pipe felt kind of weak. I called K&N and talked to a performance rep and he said right away when I told him what it was doing that they are getting new hoses because they knew the ones that came with it were getting sucked shut under boost. They said they would overnight ship me the new one in 1-2 weeks. Other than that ok
