Series 50 NextGen 2.3L Cold Air Intake with High-Flow Oiled Air FilterFOR THE 2025–2026 Ford Bronco

2025-2026 Ford Bronco 2.3L Cold Air Intake with High-Flow Oiled Air Filter

This K&N intake is offered for the 2025-2026 Ford Bronco with the 2.3L EcoBoost engine. It is not a Bronco Raptor application. The supplied oiled filter is the configuration sold here, identified by manufacturer part 50-2631.

K&N builds this intake around the engine application and filter configuration named above. Its molded plastic intake route gives incoming air a different path from the original system. The filter and tube are selected together as a kit, so a filter element by itself is not the same purchase as this intake. The 2.3L, 2.7L, and Raptor versions have different application listings and should not be treated as interchangeable.

The intake can make turbo and induction sounds easier to hear as airflow rises under load. That sound change does not tell you how much horsepower the vehicle gained. Any published power result applies to a particular test vehicle and set of conditions. Correct mounting, secure clamps, and intact seals remain essential after installation. Where the system reuses a sensor or vent connection, transfer it exactly as the instructions show rather than leaving a port open.

K&N reports gains of up to 14.3 hp at 4,900 rpm and 9.7 lb-ft at 4,350 rpm without a tune, with an airflow increase of up to 52.96%. Published test figures can vary with conditions and vehicle configuration; they are not guaranteed gains for every installation.

Why choose this intake?

• K&N reports gains of up to 14.3 hp at 4,900 rpm and 9.7 lb-ft at 4,350 rpm without a tune, with an airflow increase of up to 52.96%.
• Molded plastic intake route for the listed engine
• Supplied filter matches this exact kit configuration
• No engine tune listed as required
• Application-specific mounting and connections
• Serviceable filter with a media-specific cleaning procedure

Filter care

This version uses an oiled filter. Use the filter maker’s specified cleaner and oil, allow the element to dry fully after washing, and apply only the amount of oil instructed. More oil is not a substitute for correct service. Inspect the sealing surface before reinstalling the filter so dirt cannot bypass the element. Dusty trails can require attention sooner than normal paved-road driving. Check the intake after a dusty outing and after work near the airbox. A loose clamp, damaged seal, or poorly seated lid should be corrected before continued use.

Installation and fitment

Select this kit by its engine and years, rather than by trim badge alone. A Badlands, Outer Banks, or Big Bend badge does not by itself identify the intake connections; the engine application is the deciding detail. Existing aftermarket plumbing, a snorkel, or an engine-bay accessory can change available space. Check those interfaces before removing the factory system.

Work with the engine cool and follow the instructions for manufacturer part 50-2631. Keep dirt out of open intake connections during the swap. Before starting the engine, check each clamp, mounting point, sensor connection, and vent hose that was disturbed. After the first drive, inspect the connections again for movement or contact with nearby components.
