Banks Power 20-21 Ford F250/F350/F450 6.7L RAI, Ram Air Intake System - Dry Filter

The Banks Power 41849-D is the dry-filter build of the Ram-Air intake for 2020-2021 Ford Super Duty trucks with the 6.7L Power Stroke. Buyers looking at this part number usually want the airflow of an aftermarket intake without ever handling filter oil, often because the truck lives on dusty job sites, farm roads or gravel, or because they have seen an oiled filter foul a mass air flow sensor before.

How this intake works on the third-gen 6.7L

On these trucks, outside air enters through a forward inlet behind the grille. The Banks kit keeps that factory inlet and swaps everything downstream: a sealed two-piece XLPE airbox, a large filter element, a plastic tube to the turbo, and a silicone elbow with a bellows section so the engine can rock on its mounts without stressing the tube. Since the housing is enclosed, the turbo draws air from outside the hot engine bay. Banks claims 36 percent more mass air flow than stock and 537.3 cubic inches of filter volume. Treat those as the manufacturer's own numbers.

Dry filter versus oiled: what changes

• The D suffix in 41849-D marks the dry synthetic media version; the plain 41849 uses an oiled filter
• No oil to apply, so there is no risk of over-oiling and coating the MAF sensor
• Service is simpler: tap or blow out loose dirt, or wash with a dry-filter cleaner and let it air dry
• The housing, tube and fitment are the same as the oiled kit; only the filter media differs

Before you order

The stock intake on a 2020-up 6.7L does not wear out, so think of this as an upgrade for towing, airflow and filter life rather than a fix. If the truck has a check engine light, low power or a regeneration issue, chase that down first; an intake will not cure a failed sensor. Banks lists the kit as no tune required and states it will not set a check engine light. If you are pulling heavy loads, also check the condition and level of your transmission fluid, since the 10R140 behind this engine works hardest under the same conditions that make an intake worthwhile.

Fitment

Our listing title covers 2020-2021 Ford F-250, F-350 and F-450 with the 6.7L Power Stroke diesel. Retail listings for the same 41849-D part show 2020-2022 F-250 and F-350 pickups, left-hand drive only. If you own a 2022, an F-450 pickup, or a cab-chassis truck, send your year and VIN before ordering so we can confirm it lines up with your front end. It does not fit the 2017-2019 trucks, which take the Banks 41890-D dry-filter intake, or the 7.3L gas trucks. If you prefer an oiled element, the same kit is sold as the Banks 41849 oiled-filter Ram-Air intake.

Install notes

• Budget about an hour, a little longer on a first install. Basic hand tools only, no cutting or drilling.
• Disconnect the battery and the MAF connector, then lift out the factory box and tube as one piece if possible.
• Move the MAF sensor to the Banks tube with clean hands and do not touch the sensing element.
• Push the silicone elbow fully over the turbo inlet before tightening; a loose coupler lets in unfiltered air.
• Recheck every clamp after the first week of driving, once the silicone has heat-cycled.

While you have the truck in for service, the 6.7L Power Stroke 10R140 transmission filter kit and the 10R140 filter and pan gasket kit are worth a look for trucks that tow or have passed their first transmission service interval.

Do I ever need to oil the 41849-D filter?

No. It uses dry synthetic media. Clean it with a dry-filter cleaner or low-pressure air and let it dry; never add filter oil.

Does it fit my 2022 F-250?

Retail listings for 41849-D cover 2020-2022 F-250 and F-350 6.7L trucks, while our title lists 2020-2021. Send your VIN and we will confirm before you order.

Is a tune required?

No. Banks lists the kit as no tune required and states it does not set a check engine light.

Is the dry filter better for dusty roads?

Dry media is a popular choice for dusty conditions because there is no oil for dust to cake onto and no risk of oil reaching the MAF sensor. Inspect it more often if you run gravel daily.

Will it fit a 2019 Super Duty?

No. The 2017-2019 trucks use Banks part 41890-D for the dry version.
