Flashark Cold Air intake kit for 2017-2019 Ford F250 F350 F450 F550 V8 6.7L Powerstroke Diesel
The factory intake on the 2017–2019 6.7L Powerstroke Super Duty is a plastic airbox housing a paper panel filter, feeding a turbocharger that moves enough air to support 440 HP and 925 lb-ft of torque from the factory. At stock power levels the OEM setup is adequate — but as soon as you tow heavy, run a tune, or push sustained boost through the engine, the factory paper filter becomes a restriction and the plastic airbox traps heat-soaked engine bay air. On a diesel, hot intake air means higher EGTs, reduced turbo efficiency, and less power density per compression stroke.
This Flashark cold air intake addresses the weak points of the factory setup with three changes: (1) the restrictive paper panel filter is replaced by a high-flow washable cone filter with significantly more surface area, (2) the enclosed plastic airbox is replaced by a heat shield enclosure that isolates the filter from radiant engine bay heat, and (3) the intake piping is smoothed and enlarged to reduce restriction ahead of the turbo compressor inlet.
The result: lower intake air temperatures at the turbo inlet, reduced restriction under sustained boost, faster turbo spool from a standing start, and a induction note that finally sounds like the 6.7L it's attached to. Fits all 2017–2019 Ford F-250, F-350, F-450, and F-550 Super Duty models with the 6.7L Powerstroke V8 diesel.
Direct bolt-on install in 45–90 minutes.
Key Features
1. Enclosed Heat Shield Airbox Design
This is not an open-element intake — it includes a formed metal heat shield that surrounds the cone filter and seals against the hood when closed. On a 6.7L Powerstroke, the turbocharger and exhaust manifold radiate substantial heat into the engine bay during sustained towing or hard acceleration. The heat shield isolates the filter from that radiant heat, drawing cooler ambient air from the factory fresh-air inlet. Cooler intake air = denser oxygen charge = more power per combustion event and lower EGTs under load.
2. High-Flow Washable Dry Cone Filter
The filter element replaces the factory flat paper panel with a cone design that provides significantly more filtration surface area. More surface area means less restriction at the same airflow volume, which is critical for a turbodiesel moving the kind of air mass the 6.7L demands under boost. The dry media design requires no oil — no maintenance schedule, no risk of over-oiling contaminating the MAF sensor, and no replacement cost. When dirty: wash it, dry it, reinstall.
3. Black Powder-Coated Aluminum Intake Piping
The intake pipe is constructed from mandrel-bent aluminum with a black powder-coated finish. The powder coating provides a durable, corrosion-resistant surface that stands up to the heat and vibration of a diesel engine bay — unlike polished aluminum, which can oxidize and dull over time in this environment. The black finish pairs with the red filter for a clean, purposeful look. The mandrel-bent construction means the interior bore stays at full diameter through every bend, unlike crush-bent pipes that neck down at the curve.
4. Reduced Intake Restriction — Faster Turbo Spool
The factory paper panel filter and restrictive intake snorkel create measurable vacuum ahead of the turbo compressor — particularly at low RPM and high-load conditions where the engine is pulling hard against a restriction the turbo hasn't spooled through yet. By reducing that restriction, the Flashark intake allows the turbo to build boost faster from a standing start and from part-throttle roll-on, which translates directly to better towing response and daily driving manners.
5. Lower Intake Air Temperatures Under Load
Diesel engines are sensitive to intake air temperature — hot intake air reduces the density of the oxygen charge entering the cylinders, which raises EGTs, reduces peak power, and forces the ECU to pull fuel to protect the engine. The Flashark heat shield enclosure, combined with the removal of the heat-soaking plastic airbox, delivers a measurable reduction in intake air temperature at the turbo inlet during sustained towing and heavy acceleration.
6. Bolt-On Installation — No Tuning Required
The kit is designed as a direct replacement for the factory airbox and intake tract. All mounting points reuse factory bolt locations. The MAF sensor and any existing sensor ports are retained in their original positions on the Flashark pipe. No cutting, no drilling, no fabrication. The factory ECU adapts to the increased airflow naturally without requiring a tune — although pairing this intake with a tuner (SCT, EZ Lynk, etc.) will extract the maximum benefit.
7. Deeper, More Audible Turbo and Induction Sound
The factory airbox and intake resonator are deliberately designed to mute turbo spool and induction noise for cabin comfort. Removing those components reveals the 6.7L Powerstroke's natural character — a deep, throaty intake note under acceleration and audible turbo spool that communicates exactly what the engine is doing. Cabin noise at highway cruise remains civil; the increased volume is limited to acceleration events.
8. Truck-Specific Fit — Not a Universal Kit
This intake is engineered for the 2017–2019 Super Duty engine bay geometry specifically. The heat shield mounting points, intake pipe routing, and filter position are designed to work with the 6.7L Powerstroke's factory fresh-air inlet and hood clearance in the F-250/F-350/F-450/F-550 platform. It is not a universal-fit kit with generic brackets.

All cab configurations (Regular Cab, Super Cab, Crew Cab), all bed lengths, and all drivetrain configurations (4x2, 4x4) are compatible. The intake routing and heat shield mounting points are identical across all Super Duty chassis variants within the 2017–2019 model years.
Q: Will this fit my 2018 Ford F-250 Super Duty 6.7L Powerstroke?
A: Yes. This intake fits all 2017–2019 Ford F-250 Super Duty equipped with the 6.7L Powerstroke V8 diesel, in all cab configurations (Regular Cab, Super Cab, Crew Cab), all bed lengths, and both 4x2 and 4x4 drivetrains. The intake routing, heat shield mounting points, and filter position are identical across all F-250 variants within these model years.
Q: Will this fit a 2020 or newer F-250?
A: No. Ford updated the 6.7L Powerstroke's intake tract, airbox mounting points, and under-hood packaging for the 2020 model year Super Duty. While the engine itself is similar, the intake routing and heat shield mounting geometry are different enough that this 2017–2019 kit will not bolt on to a 2020+ truck without modification. Contact support@flasharkracing.com if you need a 2020+ compatible intake.
Q: Do I need a tune to run this intake?
A: No — a tune is not required for safe operation. The factory MAF sensor reads the new airflow volume correctly, and the 6.7L Powerstroke ECU adjusts fueling in closed-loop operation. You'll feel improved throttle response and slightly faster turbo spool on a stock tune. However, the real power benefit comes when this intake is paired with a tuner (SCT, EZ Lynk, etc.) — the increased airflow removes one of the intake-side restrictions that limits what a performance tune can deliver.
Q: What type of air filter does this use — oiled or dry?
A: Dry filter — no oil required. The red cone filter uses a dry media design that is washable and reusable. The dry design is particularly well-suited to a diesel application: diesel engines pull enormous air volume under boost, and an oiled filter in this environment can shed filter oil into the intake tract, potentially contaminating the MAF sensor. A dry filter eliminates that risk entirely. To clean: remove the filter, wash with mild soap and water, let it dry completely, and reinstall.
Q: How much horsepower will I gain?
A: Realistically, 5–15 HP and 10–25 lb-ft of torque on a stock-tuned 6.7L Powerstroke from the intake alone. The gains come from reduced intake restriction allowing the turbo to build boost faster and sustain it with less compressor effort. Throttle response improvement is more noticeable than the peak number — the truck feels more eager off the line and during part-throttle roll-on. When paired with a tuner, this intake removes one of the intake-side airflow limits, allowing the tune's higher boost and fueling targets to be reached. Claims of "20% HP gains" or "50% better fuel economy" from an intake alone on a modern turbodiesel are not realistic and we will not make them — this intake improves airflow, and airflow improvement translates to modest, real performance gains.
Q: Will this improve my fuel economy?
A: On a stock-tuned 6.7L Powerstroke, the fuel economy improvement from an intake alone is minimal — typically 1–3% at best, and only if your driving style doesn't change (the improved throttle response tends to encourage a heavier right foot, which negates any MPG improvement). The more meaningful efficiency benefit comes when this intake is paired with a tuner and used for towing — lower intake restriction means the turbo doesn't work as hard to maintain boost under sustained load, which can translate to marginally better fuel consumption on long highway tows. Do not expect this intake alone to noticeably change your fuel bills.
Q: Does the heat shield actually make a difference?
A: Yes — on a diesel, it matters more than you might think. The 6.7L Powerstroke's turbocharger, exhaust manifold, and downpipe radiate significant heat into the engine bay, especially during sustained towing or hard acceleration. Without a heat shield, an open-element intake filter would pull in 150°F+ heat-soaked air directly, reducing power density and raising EGTs. The Flashark heat shield physically separates the filter from the hot side of the engine bay and seals against the closed hood, forcing the filter to draw from the factory fresh-air inlet instead. The result is intake air temperatures 20–40°F lower at the turbo inlet under sustained load compared to an open-element intake on the same truck.
Q: Can I install this myself?
A: Yes. Plan 45–90 minutes depending on experience level. You need basic hand tools: 10 mm and 12 mm sockets, a flathead screwdriver for hose clamps, and a ratchet with extensions. Key steps: remove the factory airbox lid and paper filter, unbolt the factory airbox base, disconnect the intake snorkel from the turbo inlet, install the Flashark heat shield using factory bolt locations, mount the aluminum intake pipe to the turbo inlet with the silicone coupler, attach the cone filter inside the heat shield, connect the MAF sensor, and close the hood. No lift is required — all work is done from standing height in the engine bay. No ECU reset is required; the truck adapts naturally within a few drive cycles.
Q: How does this compare to S&B or Banks Power intakes?
A: S&B Filters and Banks Power cold air intake kits for the 6.7L Powerstroke typically cost $300–$450+. They use comparable enclosed airbox/heat shield designs with washable filters. S&B offers a clear lid option for visual filter inspection; Banks is known for their Ram-Air scoop integration. The Flashark delivers the same core benefit — enclosed heat shield intake with a high-flow washable filter reducing restriction ahead of the turbo — at roughly one-third to one-half the price. The trade-offs: S&B and Banks carry strong diesel community brand recognition, offer longer warranty terms, and Banks integrates proprietary flow-testing data into their marketing. Flashark includes a 1-year warranty and US-based email support. At $128, the Flashark is the highest-value enclosed intake option on the 2017–2019 6.7L Super Duty platform.
Q: Will this void my truck's warranty?
A: Under the Magnuson-Moss Warranty Act in the United States, a vehicle manufacturer cannot void your warranty simply because you installed an aftermarket part — unless they can prove the aftermarket part directly caused the failure. An intake is considered a bolt-on replacement part, not an engine modification that alters factory operating parameters. However, if an intake-related failure occurs (unlikely — it's a pipe and filter), Ford could theoretically deny coverage for that specific component. In practice, thousands of 6.7L Powerstroke owners run aftermarket intakes, including those still under factory warranty, without issues.
Q: Is the filter safe for dusty off-road or construction site conditions?
A: The dry media cone filter provides adequate filtration for normal on-road and light off-road use. It is not a heavy-duty pre-filter setup like you'd find on a dedicated off-road or agricultural application. If you operate your Super Duty regularly in extremely dusty conditions — gravel pits, construction sites, dry desert environments — we recommend inspecting the filter every 3,000 miles or monthly, and increasing the cleaning frequency accordingly. For sustained heavy-dust environments, consider adding a hydrophobic filter sock or pre-filter wrap (sold separately) over the cone filter for an additional layer of protection.
Q: What's your return policy and warranty coverage?
A: Flashark offers a 30-day return policy — if you're not satisfied, return the intake in unused, original condition for a full refund with no restocking fee. The intake kit is covered by a 1-year limited warranty against manufacturing defects including pipe deformation, weld cracks on the heat shield, coupler failure, and clamp corrosion. This warranty does not cover filter media wear (consumable item), or damage from improper installation, collision, or misuse. US-based email support is available at support@flasharkracing.com for fitment questions, installation guidance, and warranty claims.
