1997–2003 Ford F-150 and Expedition 4.6L/5.4L V8 Cold Air Intake
Give your 1997–2003 Ford F-150 or Expedition 4.6L/5.4L V8 a washable dry filter and a heat-shielded intake layout for daily driving, hauling, and towing. This Flashark cold air intake kit replaces the factory intake plumbing with a black 3.5-inch aluminum tube, a fender-side cone filter, and dual steel heat shields.
Expect a deeper intake tone under acceleration and a filter you can clean without oil. Review the exact vehicle fitment, kit specifications, and included parts below before ordering.

Key Features
- Mandrel-bent aluminum tube: The 3.5-inch black powder-coated tube replaces the factory plastic intake plumbing with a smooth-wall metal route.
- Washable dry filter: The red cone filter can be cleaned and reused without oil, helping avoid oil residue near the MAF sensor.
- Dual steel heat shields: The two-piece fender-side layout helps separate the filter from engine-bay heat; intake temperature depends on driving conditions.
- Factory MAF arrangement: The tube incorporates a CNC-machined MAF housing intended to preserve the factory sensor arrangement; check the seal and sensor connections during installation.
- Two breather hoses: The included 700 mm and 800 mm hoses connect the kit to the Triton breather routing.
- Straight and reducer couplers: Silicone couplers, narrow-band clamps, and stainless T-bolt clamps provide the supplied tube connections; tighten and inspect every joint.
- Factory ECU use: The kit is intended for a bolt-on installation with the factory ECU; confirm sensor and fuel-trim behavior after installation.
- Factory mounting points: The included hardware supports installation without cutting or drilling, with a typical installation time of approximately 60 minutes.
Who This Kit Is For
This kit is for the Ford F-150 and Expedition V8 applications in the Fitment table when the original intake and sensor layout match. It suits drivers who want a reusable dry filter, a black aluminum intake tube, and a deeper intake tone under acceleration. For other Ford intake options, browse Ford air intake kits.
Check Before Ordering
- Match the vehicle year, model, 4.6L or 5.4L V8 engine, and original intake layout. For a 2003 Expedition, confirm the original intake layout with our support team before ordering.
- For F-150, check the factory intake routing on Regular Cab, SuperCab, or SuperCrew and on 2WD or 4WD vehicles. The kit is not for 2004-and-newer F-150, 2004-and-newer Expedition, F-250/F-350 Super Duty, or 3-valve Triton applications.
- Reuse your factory MAF sensor and inspect its connection, coupler seals, breather connections, and idle after installation. If your vehicle has an aftermarket throttle body or altered sensor layout, compare the parts before ordering.
- Clean the dry filter without oil and allow it to dry completely before reinstalling. Dusty service can call for more frequent inspection than the typical 15,000–20,000-mile interval.
- Check your local emissions rules before ordering. Avoid deep water crossings; water ingestion can cause hydrolock and severe engine damage.
