The factory intake on the 2004–2008 Ford F-150 5.4L Triton 3V was designed for cabin quietness, not airflow. A maze of baffles, resonator chambers, and a restrictive paper filter chokes the engine right where it needs to breathe — especially under load when towing, hauling, or climbing a grade.

Flashark's cold air intake replaces the entire factory system with a mandrel-bent aluminum intake tube finished in black powder-coated for heat resistance and corrosion protection. The oversized dry high-flow filter eliminates the restrictive paper element, allowing the 5.4L to pull air with less effort. The result is 5-10 WHP gain on an otherwise stock truck, with noticeably sharper throttle tip-in and a deep, satisfying induction growl under acceleration.

Installation is a straightforward bolt-on using factory mounting points — no cutting, no drilling, no tune required. The reusable dry filter can be cleaned in minutes with compressed air and requires servicing every 15,000–20,000 miles under normal conditions. Whether your F-150 is a daily driver, weekend hauler, or jobsite workhorse, this is one of the highest-value breathing upgrades you can make to a 5.4L Triton.

Key Features

Black powder-coated aluminum intake tube — corrosion and heat resistant, engineered for long-term durability under the hood

Oversized dry high-flow air filter — maximum airflow without oil contamination risk to the MAF sensor

Mandrel-bent tubing — smooth internal diameter maintains consistent airflow velocity through every bend

5-10 WHP gain — honest, repeatable power increase on an otherwise stock 5.4L Triton 3V

Sharper throttle response — reduced intake restriction means less lag between pedal input and engine reaction, especially noticeable under load

Aggressive induction sound — deep growl at wide-open throttle, quiet at cruising speed

Utilizes factory mounting points — no cutting, drilling, or permanent modification required

No tune required — plug-and-play installation on the stock ECU (tuning optional when paired with exhaust/headers)

Reusable dry filter — clean with compressed air, service interval 15,000–20,000 miles under normal conditions

Complete hardware kit included — all clamps, couplers, hoses, and mounting brackets in the box
