K&N F-150 5.0L Performance Cold Air Intake

A cold air intake replaces the factory airbox and tube with a less restrictive setup that pulls in cooler air from outside the engine bay. Cooler, less restricted air burns more efficiently, which is where the small power gain comes from.

why this one — K&N's own dyno testing against a stock intake shows a modest but real gain (+10.51 hp / +10.69 tq) on the 2021-2023 5.0L. It's sold through Steeda as an authorized K&N dealer. It's a common first step and commonly paired with a tune, though this row does not include one.
