2003-2007 F250 & F350 6.0L K&N Performance Air Intake KN-57-2546-1

Increase Horsepower And Fuel Economy

You can always trust the brilliant engineers over at K&N to design the best in intake systems, and this performance intake system for the 2003-2007 6.0L Powerstroke is proof of that. The 57-Series intakes are up-gunned versions of K&N's more standard cold air intake kits. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow, allowing your truck's engine to inhale a larger amount of air than the restrictive OEM air filter assembly. On top of their impressive power gains, this Cold Air Intake Kit improves your truck's fuel economy so you aren't sacrificing a thing for your performance gains.

Performance K&N Filter with Heat Shield

K&N uses a massive air filter for their 57-Series CAI that is housed in an air dam to keep out any radiant heat from your engine. The filter is one of K&N's high-flow models that is washable and reusable for the life of your truck. This filter brings in a much larger volume of air than stock along with improved filtration. Along with the filter, each K&N 57-Series kit comes with a full heat shield to promote the flow of cooler air into your F250 or F350 Powerstroke engine.
