The K&N AirCharger 63-2597 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N air intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle’s engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-2597 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous air box space. This allows cooler, denser air to be directed through a custom molded air intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Fits very nicely, a bit noisier then stock.

Every vehicle I've ever owned has had K&N installed. My new 2017 F-250 SD Platinum is no different. It was so easy with the tools K&N recommended to uninstall the factory air intake and install the new. I currently have 2400 miles on truck. It looks awesome and I can tell the difference. Awesome job as usual Team K&N. Keep up the great work. How would you like to work with a noose around your neck and restrict your breathing? Get a K&N and feel the difference.
