Flashark Cold Air Intake for 1997-2003 Ford F-150 / 1997-2002 Expedition 4.6L/5.4L (V8 Engine)

Flashark 3.5" Cold Air Intake for 1997–2003 Ford F-150 / 1997–2002 Ford Expedition — 4.6L & 5.4L Triton V8

Your Triton V8 was built to work. Whether you're towing a trailer, hauling lumber, or just daily-driving an old reliable Ford, the factory intake is holding it back. That plastic snorkel and restrictive paper filter were designed for noise compliance, not for the 4.6L or 5.4L Triton to breathe.

Flashark's 3.5" cold air intake replaces the factory plumbing with a mandrel-bent 89mm aluminum tube — black powder-coated for a clean, factory-like look that won't show dirt after a decade of use. The dual steel heat shields isolate the filter from the engine bay, pulling cooler air from the fender well. Intake temps drop 15–25°F, which on a naturally aspirated V8 means more consistent throttle response and improved low-RPM torque — right where you tow and haul.

The dry, reusable cone filter needs no oil. Clean it with soap and water, let it dry, and reinstall. No MAF contamination, no check engine light, no idle hunting. The CNC-machined MAF housing is calibrated to match the factory Triton ECU, so your truck runs exactly as Ford intended — just with more airflow and a deeper V8 growl under throttle.

Installation is about 60 minutes with basic hand tools. Every bracket, coupler, breather hose, and clamp is in the box.

Key Features

• 3.5" (89mm) mandrel-bent aluminum intake tube — black powder-coated finish, smooth interior walls; maximizes airflow for both 4.6L and 5.4L Triton V8 engines
• Dry high-flow cone filter (red) — washable, reusable, no oil required; won't foul your MAF sensor; clean every 15,000–20,000 miles
• Dual steel heat shields — two-piece design isolates filter from engine bay heat; routes intake to fender-well cold air; 15–25°F intake temp reduction
• Precision MAF calibration — CNC-machined 89mm housing delivers clean laminar airflow; no CEL, no idle surging, no hesitation
• Two breather hoses included — φ16×700mm and φ16×800mm, direct-fit for Triton PCV routing; no parts store runs needed
• Straight + reducer silicone couplers — multi-layer black silicone with stainless T-bolt clamps; leak-free seal under load
• No tune required — plug-and-play with factory ECU; 4.6L and 5.4L Triton PCM adapts fuel trims automatically
• Bolt-on installation — factory mounting points, no cutting or drilling; ~60 minutes with basic hand tools
