Cold Air Intake for Ford F150 F250 (1997-2003) Expedition (1997-1999) 4.6L 5.4L Engines

Cold Air Intake Kit for Ford F-150 / F-250 / Expedition V8 More Power And Breathing Ability

This cold air intake kit is designed to replace the factory air box on 1997–2003 Ford F-150, F-250, and Expedition models equipped with 4.6L or 5.4L Triton V8 engines. The system reduces intake restriction by using larger diameter aluminum piping and a high-flow air filter, allowing cooler, denser air to reach the engine. This results in improved throttle response, increased airflow efficiency, and measurable gains in horsepower and torque across the RPM range.

The intake uses T304 aluminum construction with mandrel-bent piping to create a smooth, unrestricted path for incoming air. The design minimizes heat absorption from the engine bay while maintaining proper filtration. The high-flow air filter is washable and reusable, eliminating the need for replacement filters during routine maintenance intervals.

Performance & Design

The system is engineered to improve airflow efficiency by reducing restriction in the intake path. Testing under controlled conditions has shown potential gains of up to 10% in horsepower and torque, though actual performance improvements will vary based on vehicle condition, elevation, ambient temperature, and existing modifications. The intake produces improved throttle response particularly during acceleration and under load conditions such as towing or hauling.

T304 aluminum construction provides corrosion resistance and reduces weight compared to factory components. The mandrel-bent tubing maintains consistent internal diameter throughout each bend to minimize turbulence and pressure loss. The open-element filter design allows increased airflow while producing a more audible induction sound during acceleration.

Features & Components

What's Included

• T304 polished aluminum intake pipe
• High-flow washable air filter
• Mounting hardware and clamps
• Installation instructions

Installation

• Direct replacement for factory air intake system
• Uses existing factory mounting points
• No cutting or drilling required
• Installation time approximately 45–60 minutes
• Basic hand tools required (screwdrivers, socket wrenches)

Installation Note:
After installation, disconnect the negative battery terminal for approximately one minute to allow the engine control unit to reset and adapt to the modified airflow characteristics. This allows the ECU to recalibrate fuel and ignition timing for optimal performance with the new intake system. Always disconnect the battery before performing any engine bay work.

Filter Maintenance

The washable air filter can be serviced approximately every 50,000 miles under normal driving conditions. To service, remove the filter from the intake pipe, apply appropriate filter cleaning solution, rinse thoroughly with water, allow to dry completely, re-oil according to specifications, and reinstall. This eliminates the need for replacement filters and reduces long-term maintenance costs.

Material Specifications

The intake pipe is constructed from T304 aluminum, which provides resistance to corrosion and heat in the engine bay environment. The polished finish provides both aesthetic appeal and additional protection against oxidation. Mandrel-bent construction ensures smooth internal surfaces without crimping or flow restriction at bend points.

This cold air intake kit provides improved airflow characteristics for 4.6L and 5.4L Triton V8 engines while maintaining reliable filtration and a direct-fit installation. The system is designed to work with factory engine management systems without requiring additional tuning or modifications.
