The K&N 50-2629 NextGen Cold Air Intake is a Series 50 GEN3 system built for the 2.3L L4 in the 2024 Ford Ranger. It replaces the factory airbox with a semi-enclosed NextGen housing that draws air through a larger fresh-air inlet and shields the filter from engine-bay heat. Its oversized, radius-entry oiled cotton gauze filter and large-diameter black HDPE intake tube are meant to deliver more air to the engine.
K&N's own dyno testing lists gains of +15.7 hp, +21.47 lb-ft of torque, and +35.87% airflow (CFM). Owners on user forums describe a gain in that range and note that the stock intake tube pulls warm air from the engine bay, which is the main reason to upgrade. Expect some heat soak at idle, since owners report the hood does not fully seal the airbox. The filter is washable and reusable, so buyers can skip recurring filter purchases. Owners also warn that over-oiling a cotton filter can contaminate the mass airflow sensor, so the oil should be applied sparingly.
This intake fits the 2024 Ford Ranger L4 2.3L, and published model-year coverage differs between sources, so confirm your exact year and trim with K&N before ordering. The manufacturer states the system is not legal for sale or use in California on pollution-controlled vehicles. K&N says a typical installation takes around an hour, and an installation instruction sheet is available for this part. Long-tail searches such as 2024 Ranger 2.3 EcoBoost cold air intake, K&N 50-2629 install, and oiled cotton gauze intake filter should lead to this listing.
The manufacturer states that the 50-2629 is not legal for sale or use in California on any pollution-controlled motor vehicle.
The manufacturer describes the High-Flow LIFETIME filter as washable and reusable. Owners on user forums say cleaning and re-oiling the filter takes time and that the filter must dry before reuse. They also warn that excess oil can reach the mass airflow sensor, so use only light oiling.
K&N's dyno testing reports +15.7 hp and +21.47 lb-ft of torque. Owners on user forums report gains in a similar range, and results vary by truck and conditions.
K&N states that a typical installation takes around an hour, and the manufacturer publishes an installation instruction sheet for this part. Review that sheet before you start, because the exact tool list and step count for the 2024 2.3L application were not confirmed in our research. Owners on user forums report that the hood does not seal the airbox, so check that the intake sits securely and clears the hood and engine-bay components. Keep oil away from the mass airflow sensor and the tube connection points when you handle the oiled filter.
