This FLASHARK cold air intake system is custom-designed for 1999-2003 Ford Excursion and F-Series Super Duty trucks equipped with the 7.3L V8 Powerstroke diesel engine. It replaces the restrictive factory airbox with a high-flow aluminum intake tube and reusable dry filter, delivering cooler, denser air to your engine for measurable gains in horsepower, torque, and throttle response — whether you're towing, hauling, or daily driving.
Key Features
- Mandrel-Bent Aluminum Intake Tube: Smooth, unrestricted airflow path maximizes oxygen delivery; heat-resistant coating prevents heat soak from the engine bay
- Reusable Dry Cotton Gauze Filter: Traps up to 99% of contaminants with no oil required; washable and reusable for 50,000+ miles with simple maintenance
- 100% Bolt-On Installation: Retains all factory MAF sensor and mounting points; no cutting, no wiring modifications, no ECU tuning required
- Included Heat Shield: Blocks hot air from the engine bay, ensuring intake air stays cool for optimal combustion efficiency
- Enhanced Turbo Sound: Delivers a deep, aggressive intake and turbo spool sound under acceleration, while remaining quiet during cruising
- Fuel Efficiency Improvement: Optimized air-fuel ratio helps reduce EGTs and improve MPG during highway driving and towing
Frequently Asked Questions
Q: Does this intake require a custom tune? A: No. This is a true bolt-on upgrade for the 7.3L Powerstroke. No ECU tuning is required to realize performance gains.
Q: Will this fit my early 1998 F-350? A: Only if your 1998 truck was manufactured after December 7, 1998. Early 1998 models use a different MAF sensor bracket and are not compatible.
Q: How do I clean the dry filter? A: Use low-pressure compressed air or mild soap and water. Allow to fully dry, then reinstall. No re-oiling is needed or recommended.
Q: Does it include all installation hardware? A: Yes — all clamps, brackets, heat shield, and hardware are included. No extra parts are required.
Q: Will this improve my towing performance? A: Yes. The increased airflow and reduced restriction help maintain power under load, improving throttle response when towing heavy trailers.
⚠️ IMPORTANT COMPATIBILITY WARNING This intake kit WILL NOT FIT any Ford vehicle manufactured before December 7, 1998. Please verify your vehicle's build date on the driver's door jamb sticker before ordering.
