Detailed Product Description

The K&N 57-2595 is a performance air intake system designed around the 57 Series FIPK platform. Its molded intake tube, stainless steel worm-gear clamps, and included couplers create a purpose-built intake path for the Ford Expedition and Lincoln Navigator fitments listed here. K&N states this design can increase horsepower and torque, with an estimated gain of 6.94 HP at 4100 RPM and a stated 7 HP increase.

The filter uses oiled cotton gauze media and is washable and reusable, with a replacement filter reference of RU-5173. The system is packaged with the needed intake tube ports for the specified applications, and the MAF sensor adapter is included when required. If you are searching for a Ford Expedition cold air intake or a Lincoln Navigator performance intake, 57-2595 is the relevant part number to verify against your application.

What This Intake Helps Address

• Restricted airflow through the factory intake path
• Heat-soak exposure from the engine bay
• Need for a reusable filter serviceable over time
• Loss of intake efficiency under higher engine demand
• Fitment verification for a CARB-exempt intake on the listed vehicles
