K&N Performance Air Intake for 2011-2019 Ford Ranger 3.2L Diesel | +16HP Gain

Boost your Ford Ranger 3.2L L5 Diesel with K&N 57S-4001. Guaranteed horsepower increase, improved torque, and a washable lifetime filter.

The K&N 57S-4001 Performance Air Intake System (Generation II) is the ultimate upgrade for 2011-2019 Ford Ranger owners looking to enhance their vehicle's power and efficiency. Designed to replace the restrictive factory air box and intake path, this system features a custom-molded, high-density polyethylene (HDPE) tube that streamlines airflow directly into the engine.

By reducing air turbulence and temperature, this kit provides a dyno-tested increase of approximately 16.2 HP and 81.3 NM of torque at 1850 RPM. At its core is an oversized, conical K&N High-Flow Air Filter™ made from multi-layered oiled cotton, ensuring superior filtration while allowing a massive volume of air to pass through. Encased in a protective enclosed air box, it shields the intake from engine heat, ensuring your 3.2L L5 Duratorq-TDCi diesel engine breathes nothing but cool, oxygen-rich air.
