These K&N Cold Air Intake Kits for Ford Powerstroke Diesel Superduty Trucks feature K&N's Filtercharger, the world's first and still the best high-flow oiled filter, as well as rotationally molded black High Density Polyethylene tubes and heat dams to prevent hot air from being drawn into the engine. These technological efforts result in some real and noticeable gains in power and fuel economy. Actual performance gains can be affected by vehicle condition and environmental factors but owners of Ford Powerstroke equipped Superduty trucks can typically expect to have an additional +15 HP and +25ft/lbs Torque at their disposal after a fast and simple installation! Imagine the added power you will experience after eliminating that inferior stock airbox, your diesel will thank you with reduced fuel consumption and a longer service life!

K&N 77-Series metal intake kits for trucks and SUV’s combine outstanding performance and under-the-hood style. Featuring free-flowing mandrel-bent aluminum tubing, the 77-Series intakes have a highly polished aluminum finish, leading many drivers to opt for the outstanding visual appeal of these kits. The metallic finishes are bold, beautiful and last forever. Polished finish kit part #'s end in "KP".

K&N 57-Series intake kits use only non-metallic rotationally molded High Density Polyethylene tubing that reduces air temperature and decreases intake sound over a metal tube. K&N intake kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The precision engineered tube drives a massive amount of air into an engine, which translates into POWER.

K&N 63-Series Air-Charger intakes are a sister line to the 57-Series and feature the same molded HDPE construction and similar performance gains, but are not CARB exempt, making them illegal for street use in the state of California.
