Cold Air Intake Kit for 1996-2004 Ford Mustang GT 4.6L V8

Flashark Cold Air Intake Kit For 1996-2004 Ford Mustang GT 4.6L V8

The 1996-2004 Mustang GT's 4.6L SOHC V8 was Ford's first modular V8 in the Mustang — but the factory air intake never gave it room to breathe. The stock setup routes air through a restrictive plastic intake silencer, a flat-panel paper filter, and a narrow-diameter duct, all tuned for cabin quietness rather than flow. By the time air reaches the throttle body, significant velocity and density have been lost.

The FLASHARK Cold Air Intake Kit replaces this entire chain with a 3.5-inch mandrel-bent aluminum tube and a high-flow dry cotton gauze filter, shielded from engine heat by a black powder-coated steel enclosure. Dyno testing shows gains of 5-15 HP and 6-8% torque across the 4.6L's powerband — no ECU reflash required. Whether your Mustang has the early non-PI heads (1996-1998, 215 hp) or the later PI heads (1999-2004, 260 hp), the intake delivers a sharper throttle response and a deep, aggressive induction growl that the factory spent years suppressing.

Installation is a true bolt-on: 30-60 minutes with basic hand tools, factory MAF plugs directly in, and all mounting hardware is included. For the money, there is no faster way to wake up a 2V 4.6L Mustang before moving on to exhaust, gears, or a tune.

Key Features

3.5" Mandrel-Bent Aluminum Intake Tube — smooth, unrestricted airflow path replaces the factory's multi-chamber plastic silencer; black powder-coated finish for heat resistance and corrosion protection

High-Flow Dry Cotton Gauze Filter — 95% filtration efficiency, washable and reusable; no oil required, so no risk of coating the MAF sensor

Black Powder-Coated Steel Heat Shield — isolates the filter from engine bay heat soak, directs intake air toward the cooler fender well area

True Bolt-On Installation — reuses factory mounting points, MAF housing, and PCV plumbing; 30-60 minutes with hand tools, no cutting or drilling

OEM MAF & IAT Sensor Compatible — calibrated MAF housing maintains factory air/fuel ratios, no check engine light or idle issues

Aggressive Induction Sound — deep intake growl under wide-open throttle lets the 4.6L finally sound like the V8 it is
