Ford's EcoBoost V6 family — the 2.7L Nano and 3.5L D35 — is a genuinely impressive line of turbocharged engines. But their factory intake system? It's engineered for one priority above all else: silence. A maze of plastic resonators, baffle chambers, and restrictive tubing sits between the turbos and the outside air, muffling the very sound that makes a turbocharged engine exciting. Worse, that restriction adds measurable lag to turbo spool.

This Flashark cold air intake replaces that compromised factory plumbing with a black powder-coated aluminum intake tube and a high-flow dry cone filter, paired with a metal heat shield that retains the factory lower airbox ducting. The result: reduced pre-turbo restriction, faster spool response, and a turbo induction note you can actually hear — the whistle of the compressor wheels and the whoosh of the bypass valves that Ford buried under layers of plastic.

Expect 8-15 WHP on an otherwise stock truck — the 3.5L typically sees the higher end of that range due to its larger displacement and higher airflow demand. More immediately noticeable is the part-throttle sharpness: the turbos wake up sooner, and tip-in response loses that factory softness. 

Key Features

Black powder-coated aluminum intake tube — mandrel-bent for smooth, unrestricted airflow; corrosion-resistant finish engineered for daily-driver durability

High-flow dry cone filter — no oil required, cleanable and reusable every 15,000-20,000 miles under normal driving conditions

Metal heat shield — separates the filter from direct engine-bay radiant heat while preserving the factory lower air intake duct

Retains factory lower air intake box — continues drawing ambient outside air from the grille/fender inlet rather than hot under-hood air

8-15 WHP gain — honest real-world range on stock tune (3.5L typically sees upper end, 2.7L mid-to-upper); gains compound with a custom tune, cat-back exhaust, or intercooler upgrade

Faster turbo spool — reduced pre-compressor restriction means less pressure drop before the turbos; spool threshold drops noticeably, especially in the 1,800-3,000 RPM daily-driving range

Audible turbo induction — the compressor whistle and bypass valve whoosh that Ford silenced with factory resonators becomes clearly audible under acceleration; calm at cruise, aggressive under load

No ECU tune required — MAF housing diameter is matched to factory airflow calibration; fuel trims remain within the adaptive ECU range

Bolt-on install — 45-75 minutes with basic hand tools; no cutting, drilling, or permanent modifications

Electric fan compatible — designed to clear the electric cooling fan assembly on EcoBoost-equipped F-150 and Expedition (no belt-driven fan clearance issues)
