The K&N AirCharger 63-2575 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N 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 63-2575 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that mounts into the lower air box. This allows cooler, denser air to be directed through a custom molded 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 requiring only a screwdriver, socket set and several wrenches. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

 Great sound and performance added to the challenger! Easy install. Very nice.

 Great product. Easy install on a 2008 Ford Explorer. The growl of this thing is amazing and has added a few mpg as well. Want one of these in all my cars.
