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)

Q: Will this intake fit both 2.7L and 3.5L EcoBoost?
A: Yes. This kit is engineered to work with both the 2.7L Nano EcoBoost V6 and the 3.5L D35 EcoBoost V6 in the 2015-2024 F-150 and 2018-2024 Expedition. Both engines share the same intake manifold inlet diameter, MAF sensor housing, and airbox footprint on these platforms, making a single kit compatible across both displacements.
Q: Will this fit a 2021+ (14th Gen) F-150?
A: Yes. While the 2021+ F-150 received a significant exterior and interior redesign, the 2.7L and 3.5L EcoBoost powertrains, engine bay architecture, and intake airbox layout remain substantially unchanged from the 2015-2020 generation. The factory airbox mounting points, MAF sensor, throttle body connection, and lower air intake duct are all shared between generations. The kit is verified for 2015-2024 F-150 models.
Q: Will this fit a Raptor with the 3.5L High Output EcoBoost?
A: Not confirmed. The Raptor's 3.5L High Output EcoBoost shares the same basic engine architecture as the standard 3.5L but features larger turbochargers, a different intercooler system, and unique intake plumbing that may not align with this kit's tube routing. Installing a standard F-150 intake on a Raptor could result in fitment interference or unmetered airflow issues. We recommend contacting service@flasharkracing.com with your Raptor's model year to check compatibility before ordering.
Q: How much horsepower does this intake add to an EcoBoost?
A: Expect 8-15 WHP on a stock-tune truck. The 3.5L EcoBoost (375-400hp factory rating) typically sees results at the higher end — 12-15 WHP — because its larger displacement and higher airflow demand benefit more from reduced pre-turbo restriction. The 2.7L Nano (325hp factory rating) typically sees 8-12 WHP. Both gains become more pronounced above 3,000 RPM, where the factory intake's flow restriction becomes a measurable bottleneck. The real-world drivability improvement — faster turbo spool and sharper throttle response — is often more noticeable than the peak number. Gains compound significantly with an aftermarket intercooler, downpipes, and a custom ECU tune.
Q: Does this intake require an ECU tune on my EcoBoost?
A: No. The MAF housing diameter is engineered to match the factory airflow calibration, so the ECU's fuel trims remain within adaptive range without a tune. That said, an EcoBoost engine responds especially well to tuning — if you're already running or planning a custom tune (Cobb Accessport, SCT, HP Tuners, etc.), the intake's reduced restriction will allow your tuner to extract more power than with the factory airbox. For maximum gains, we recommend pairing this intake with a custom tune, but it is not required for safe daily operation.
Q: Will this intake make my EcoBoost sound different?
A: Absolutely — and for turbocharged engines, this is often the most satisfying change. The factory intake silences three distinct sounds that this kit unearths: (1) turbo compressor spool — a rising whistle as the turbos build boost, most audible from 2,000-4,000 RPM under moderate to heavy throttle; (2) bypass/blow-off valve venting — the "whoosh" when you lift off the throttle after building boost, which the factory recirculates silently; and (3) a deeper, throatier induction note at wide-open throttle. At idle and light cruise, the intake is nearly as quiet as stock — it only wakes up when you use the throttle. Your exhaust note is unchanged.
Q: Is this a true cold air intake or a short ram?
A: It's a hybrid design. The kit includes a metal heat shield that surrounds the filter and seals against the hood, and it retains the factory lower air intake duct that draws ambient air from the grille and fender well area. For a turbocharged engine, intake air temperature is less critical than for a naturally aspirated engine — the intercooler is responsible for cooling the charge air after the turbos compress it. What matters most for a turbo intake is minimizing pre-compressor restriction (pressure drop before the turbos), which this kit addresses directly with its smooth mandrel-bent tube and high-flow filter.
Q: Will this intake affect my truck's fuel economy?
A: Reduced intake restriction can theoretically support slightly more efficient combustion at steady highway speeds, but the effect is marginal on an EcoBoost — Ford's factory intake is not the primary bottleneck for fuel efficiency in a 5,000+ lbs truck. In practice, the louder turbo noise encourages harder throttle use, which will consume any theoretical MPG gain and then some.
Q: What is the hardest part of installing this intake on an F-150 or Expedition?
A: The two most time-consuming steps: (1) removing the factory intake resonator assembly — the EcoBoost intake system includes a large plastic resonator box tucked into the fender area that requires patience to extract; and (2) positioning and securing the heat shield so it seals properly against the hood when closed. Neither step requires special tools. Total install time: 45-75 minutes.
Q: How do I clean the dry filter, and how often?
A: Clean every 15,000-20,000 miles under normal street driving (every 5,000-8,000 in dusty conditions). Tap gently to dislodge debris, use compressed air (max 30 PSI) from inside outward. For heavy contamination, rinse with low-pressure water from the inside out and air-dry completely (4-6 hours). Do not apply oil to this filter. The EcoBoost MAF sensor is highly sensitive — oil contamination will cause incorrect airflow readings, lean fuel trims, and a CEL.
Q: Can this intake cause a check engine light on an EcoBoost?
A: A properly installed intake should not trigger a CEL. The three most common causes on the EcoBoost platform: (1) MAF sensor installed backwards — confirm directional arrow; (2) vacuum leak at a coupler or PCV breather connection — EcoBoost engines generate significant crankcase pressure and a small leak will trigger lean codes (P0171/P0174); (3) unmetered air entering after the MAF — check couplers, heat shield seal, and PCV connection for gaps. Disconnecting the battery for 15 minutes resets fuel trims.
Q: Will this void my Ford factory warranty?
A: Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle's warranty simply because you installed an aftermarket part. Ford would need to prove that the intake specifically caused a failure to deny a warranty claim on that specific component. In practice, a cold air intake is one of the most common and lowest-risk modifications performed on EcoBoost trucks. If you're concerned, you can reinstall the factory intake before dealership visits — the installation is fully reversible with no permanent modifications. Note that an aftermarket ECU tune carries a different warranty risk than an intake alone.
