To immediately see the benefits of a K&N air intake system, simply replace the Explorer’s original intake assembly with the 57-2573. Cooler outside air is drawn through a washable and reusable K&N chrome top air filter (RF-1048) for more power and filtering capacity.
A powder coated steel heat shield replaces the stock air box and protects the K&N air filter while isolating it from engine heat. The 57-2573 uses the OE Mass Airflow Sensor. Although the MAF is re-positioned to gain the benefits of additional horsepower, no computer programming is required. The K&N air intake system can be installed in 90 minutes or less with simple hand tools and comes with the famous K&N Million Mile Limited Warranty.
