K&N NextGen Cold Air Intake — 2025 Bronco 2.3L
More airflow, more power, and a lifetime filter — a bolt-on cold-air system engineered specifically for the 2025 Ford Bronco 2.3L EcoBoost.
Real Power, No Tune Required
K&N dyno-tested this NextGen system on the 2.3L EcoBoost Bronco and measured gains of up to 14.3 horsepower and 9.7 lb-ft of torque — straight bolt-on, no tuning or recalibration needed. The secret is airflow: a rotationally-molded high-density polyethylene (HDPE) intake tube flows up to 52.96% more air than the restrictive factory setup, so your turbo has more to work with everywhere in the rev range.

A Filter You'll Never Throw Away
The oversized conical High-Flow washable filter uses oiled cotton media that's built to last the life of your Bronco. Under normal highway driving you can go up to 100,000 miles between cleanings — and when it's finally time, you wash it, re-oil it, and drop it back in. No more buying a paper filter every service interval.
|
Cold Air, Sealed From Engine Heat
Hot air makes less power. The custom-designed NextGen air box encloses the filter and seals against the engine bay, pulling cooler, denser air into the intake instead of heat-soaked underhood air. Cooler intake charge means a more efficient burn and more consistent power — exactly what you want when you're wheeling or towing.
