Maximize your F-150's or Expedition's V8 potential with this cold air intake—delivering 7-10% more horsepower, better throttle response, and that classic V8 growl.

More Power for America's Best-Selling Truck

The tenth-generation F-150 and second-generation Expedition defined the late '90s and early 2000s—tough, reliable workhorses powered by Ford's proven Triton V8 engines. Whether you're running the 4.6L two-valve or the stronger 5.4L, your truck has more to give. This cold air intake system replaces the restrictive factory airbox with a heat-shielded, high-flow design that feeds your engine cooler, denser air for better combustion and stronger performance.

The included steel heat shield keeps hot engine bay air away from the intake, ensuring your V8 gets the coldest air possible. Combined with a lightweight polished aluminum intake tube and washable high-flow filter, this system delivers 7-10% horsepower gains and 6-8% torque improvements you'll feel every time you accelerate or tow.

Real Performance Gains

  • Power Boost: 7-10% increase in horsepower with 6-8% torque gains throughout the powerband
  • Better Throttle Response: Improved airflow delivers quicker acceleration from low to mid RPM
  • Heat Shield Protection: Durable carbon-black coated steel shield keeps intake air cool for maximum power
  • Enhanced Sound: Deep, sporty V8 intake note under acceleration that settles at cruise
  • Improved Efficiency: Better airflow can improve fuel economy during highway driving
  • Reusable Filter: Washable cone filter saves money over disposable factory filters

Complete Heat Shield System

Unlike basic intake tubes, this system includes a full heat shield that protects the filter from engine bay heat and debris. The polished T-304 aluminum intake pipe provides a smooth, unrestricted path for maximum airflow while looking great under the hood.

Direct Bolt-On Installation

This intake replaces your factory airbox using existing mounting points—no cutting or drilling required. Most installations take 60-90 minutes with basic hand tools. Everything you need is included in the kit. Disconnect your battery's negative terminal before starting to allow the ECU to adapt to the improved airflow.

Installation & Tools

The Wrench Time

  • Estimated Time: 45-60 Minutes
  • Difficulty: 3/10 - Basic bolt-on, but requires finesse with 20-year-old brittle plastics and sensitive sensors on this platform.

Tools You Will Need

  • 10mm deep socket and ratchet (for battery and airbox bolts)
  • 8mm socket or nut driver (for hose clamps)
  • T20 Torx bit (for factory MAF sensor removal)
  • Flathead screwdriver (for stubborn harness clips)
  • Silicone spray lubricant (mandatory for sensor transfer)
Mechanic’s Pro Tip (The "Gotcha"):
The 10th Gen F-Series (1997-2003) is notorious for the factory corrugated rubber intake tube cracking on the underside, causing massive vacuum leaks and those dreaded P0171/P0174 lean codes. When removing the factory setup, be incredibly careful with the IAT (Intake Air Temperature) sensor. The factory rubber grommet turns to stone after two decades of 2V Triton heat cycles. If you yank it out dry, you’ll snap the plastic probe right off. Lube it first.

Phase 1: Removing the Factory Part for the 1997-2003 Ford Expedition F-150 5.4L

  1. Disconnect the Battery: Always start by disconnecting the negative battery terminal using a 10mm wrench to prevent check engine lights and allow the ECU to reset its fuel trims.
  2. Unplug Sensors: Disconnect the electrical harnesses from the Mass Air Flow (MAF) sensor and the Intake Air Temperature (IAT) sensor. Gently push the locking tabs with a flathead screwdriver if dirt has seized them.
  3. Disconnect PCV Lines: Carefully detach the factory PCV breather hose from the air intake tube. These plastic fittings are extremely brittle on the 5.4L engine, so do not force them.
  4. Loosen Clamps: Use an 8mm socket to loosen the factory worm gear clamp securing the main intake tube to the throttle body.
  5. Remove Factory Airbox: Remove the mounting bolts securing the factory airbox to the inner fender using a 10mm deep socket. Lift the entire airbox, filter, and intake tube assembly out of the engine bay as one complete unit.

Phase 2: Installing the Cold Air Intake for Ford F-150/Expedition (1997-2003) 4.6/5.4L V8 Engines

  1. Transfer the MAF Sensor: Using a T20 Torx bit, carefully remove the MAF sensor from the factory housing. The MAF element is highly sensitive; do not touch the delicate exposed wires inside. Carefully seat it into your new Cold Air Intake tube using the supplied aftermarket hardware.
  2. Transfer the IAT Sensor: Spray a burst of silicone lubricant around the old rock-hard grommet to safely twist and pull out the factory IAT sensor. Lube the inside of the new rubber grommet on the aftermarket tube and gently push the IAT sensor into place.
  3. Install the Heat Shield: Drop the new aftermarket heat shield into the factory airbox location. Secure it tightly to the inner fender well using your 10mm socket and the provided hardware.
  4. Mount the Cold Air Intake Tube: Slide the provided silicone couplers onto the throttle body and the new intake tube. Seat the tube firmly, reconnect the PCV breather line, and tighten all clamps down snugly with an 8mm socket to prevent vacuum leaks.
  5. Reconnect and Calibrate: Plug the MAF and IAT wiring harnesses back in. Reconnect the negative battery terminal with your 10mm wrench. Start the vehicle, but do not touch the gas pedal for at least 20 seconds. Let it idle so the ECU can properly learn the new increased airflow volume without throwing a code.
