K&N 63-2589 63 Series AirCharger Kit for 2015 Ford Mustang 2.3L

The K&N 63-2589 AirCharger air intake system replaces the restrictive factory air filter and air intake housing on some Ford Mustang models. K&N air intakes are designed to dramatically reduce air intake restriction as well as smooth and straighten air flow. This allows your 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 63-2589 air intake comes with a chrome-topped K&N high-flow air filter and a heat shield that installs into the original air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for guaranteed power gain. The tube accommodates the factory crank case vent hose and air inlet temperature sensor as well as the blow-off valve. The oversized cone-shaped 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, usually in 90 minutes or less using your vehicle’s existing factory mounting points. The tools needed are a screwdriver, ratchet set and an Allen wrench. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

  • Guaranteed horsepower gain
  • Designed to improve throttle response and engine sound
  • Free-flowing high density polyethylene tube
  • Replaces entire factory air intake system
  • Easy to install, usually in 90 minutes or less
  • K&N Million Mile Limited Warranty

To Oil or Not to Oil: (That’s Not Really the Question)

By John M. Arnaud

Over the years, the air-filter experts at K&N have proven (in their in-house filtration test lab, no less) that the secret to increasing airflow to your engine without sacrificing protection lies in their exclusive air filter oil. This oil, which permeates a filter’s cotton fibers, grabs dust and other microscopic contaminants and keeps them from entering your system. Non-oiled paper filters don’t even come close.

So the question isn’t whether you should be using an oiled filter (you should); instead, you should be asking “How much should I use?” and “How do I apply it?” The answers to those questions depend on which delivery system you use: squeeze bottle or aerosol applicator. Read on for the scoop from K&N:

Squeeze Bottle

Apply the air filter oil evenly along the crown of each pleat, then allow the oil to wick for 20 minutes before touching up any light areas on either side of the filter.

Aerosol Bottle

Spray the oil evenly along the crown of each pleat, holding the spray nozzle about 3” away from the filter. Allow the oil to wick for 20 minutes, then touch up any light areas on either side of the filter.

Most K&N air filters are oiled at the factory, so reoiling shouldn’t be necessary until it’s time to clean your filter, usually at 50,000 or 100,000 miles, depending on your application. K&N’s Recharger kits contain everything you need to freshen up your filter, including filter cleaner and your choice of oil dispenser.
