K&N Cold Air Intake System Dry-Flow Filter - Boost Power & Sound

In this review of the K&N Cold Air Intake System with a Dry-Flow air filter, the bottom line is simple: this is a practical upgrade for Ford owners seeking reliable power gains and an improved engine note without the mess of an oiled filter. It is best for drivers of 2015-2025 Ford F150 models, F150 Raptor and 2021-2025 Expedition/Bronco owners who want an easy-to-install, reusable solution that promises an estimated increase up to 11HP and up to 11 ft. lbs. of torque while maintaining factory-level protection and a no-hassle maintenance cycle.

Key Features

• Dry-Flow reusable filter: Two layers of pleated synthetic media block dirt while eliminating oiling steps, so cleaning is just a wash and re-use process.
• Guaranteed performance gain: The intake provides a less restrictive airflow path, tested on wheel-based dynamometers to deliver an estimated increase up to 11HP and up to 11 ft. lbs. of torque for responsive acceleration.
• Engine sound improvement: The intake lets the engine breathe more freely so you hear a stronger growl on acceleration while it quiets at cruising speed.
• Durable construction: A roto-molded HDPE intake tube and fully enclosed air box increase airflow volume and help protect incoming air from engine bay heat.
• Long maintenance intervals: Filter cleaning is required only every 50,000 miles under normal highway driving, reducing upkeep compared with oiled filters.
• Made in the USA with warranty: Backed by a No-Hassle Lifetime Limited Warranty and compatible with the vehicle manufacturer warranty.

Who It's For

The K&N Cold Air Intake System is aimed at pickup and SUV drivers who want a straightforward, bolt-on performance and sound upgrade without complicated maintenance. It suits owners of 2015-2025 Ford F150 and F150 Raptor models and 2021-2025 Expedition and Bronco models looking for reliable gains in throttle response and highway drivability.

It is less appropriate for drivers who require strictly stock emissions calibrations for motorsport classes or those who prefer a permanently maintenance-free sealed intake; while the system is designed to protect the engine and retain warranty coverage, it does require periodic washing of the Dry-Flow element.
