The factory airbox on the 2015–2017 F-150 3.5L EcoBoost is designed for silence, not flow. Its restrictive baffles and paper filter choke the twin turbos before they even spool up — leaving torque and throttle response on the table.

The Flashark Cold Air Intake Kit replaces the entire factory intake tract with a black powder-coated aluminum mandrel-bent intake tube and a high-flow dry filter. The result: less restriction across the entire RPM range, faster turbo spool, and audible intake and bypass sounds that the stock box completely muffles. Expect 8–12 HP and 10–15 lb-ft of torque gain on the stock tune, with more available when paired with a custom calibration.

Bolt-on installation takes about 60 minutes with basic hand tools — no cutting, no drilling, no permanent modifications. Includes a heat shield to isolate the filter from engine bay radiant heat, reducing intake air temperatures under load.

Key Features

8–12 HP / 10–15 lb-ft Torque Gain — Measurable improvement on the stock tune; additional gains with custom calibration

Faster Turbo Spool — Mandrel-bent aluminum intake tube eliminates factory baffles and restrictions, letting the twin turbos breathe freely

Audible Turbo and Bypass Sounds — Open-element dry filter uncovers the induction and blow-off noises the stock airbox silences

Black Powder-Coated Aluminum Tubing — Heat-resistant, corrosion-resistant finish that looks clean under the hood and won't oxidize over time

Dry High-Flow Filter — No oil required; washable and reusable with a service interval of 15,000–20,000 miles under normal conditions

Heat Shield Included — Powder-coated steel shield isolates the filter from engine bay radiant heat, reducing intake air temperatures under load

Bolt-On Installation — ~60 minutes with basic hand tools; no cutting, drilling, or permanent modifications required

Factory MAF and PCV Compatible — Retains all factory sensor and breather connections; no tuning required for basic operation

Designed for 3.5L EcoBoost Gen 1 (2015–2017) — Not compatible with 2.7L EcoBoost, 3.5L naturally aspirated, or 5.0L Coyote engines
