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.

Product Reviews

  It is everything they said and it's easy to install; as well, as it has an outstanding performance.
Steve Milwaukee, Wisconsin
  This is the fourth K&N filter kit I have purchased for my vehicles. Every kit is very well engineered and fit perfectly. Such a nice surprise in this day and age of one size fits all. The first thing that you will notice about installing this filter is the immediate throttle response your vehicle will now have. Any little bit of hesitation or lag dissappears. Well worth the investment.

  Great product...felt the increase in power immediately, and added a cat back exhaust to further add to the power increase. The instructions were ok and overall the product fit well....just a challenge getting the filter into the air box...and the rubber channel gasket is a challenge to cut and form through the corners.

  Seems to have increased horsepower at higher RPM''s. Gas mileage has not changed. It will be interesting to see what type of performance I see when pulling the boat this coming season.
Jerry Freedom, Wisconsin
  Sounds great. Mileage improvements pulling and in town. Looks 100 times better then stock air intake with all it's extra baffles and what not. Thanks for making my truck a TRUCK!!
Jason Washington
  Great sound and performance added to the challenger! Easy install. Very nice.
Derek Fort Worth, Texas
  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.
