Banks Power 17-19 Ford F250/F350/F450 6.7L Ram-Air Intake System - Dry Filter

The Banks 41890-D is the dry element version of the Banks Ram-Air intake for 2017-2019 Ford F250, F350 and F450 Super Duty trucks with the 6.7L Power Stroke diesel. Pick this part number if you want the same housing, inlet and elbow as the oiled kit but would rather wash a dry filter than buy filter oil and re-oil the element after every cleaning. It is aimed at owners who tow, see high exhaust temperatures on long grades, or run dusty roads and want a reusable filter they can service at home.

What this intake changes on a 2017-2019 6.7L

The factory air box on this body sits behind the battery at the front corner of the engine bay, so incoming air has to work its way around the battery before it reaches the filter. Banks kept its air box in that same stock position and changed how the air gets there: a forward facing inlet ties into the factory opening, a second inlet picks up cooler air, and a sleeve over the filter element smooths flow into the box. A rubber EPDM elbow with bellows connects the box to the turbo and absorbs engine movement. Banks rates the system at a 40 percent density gain at the turbo inlet and a 49 percent gain in mass airflow compared with the factory intake. The stock mass airflow sensor mounts to the new box in its original location and orientation, which is part of how the kit keeps the truck running on the factory calibration.

Why choose the dry filter

• No filter oil to buy, apply or wait on after a wash
• Nothing to over-apply, so there is no excess oil to wick into the intake tract
• Cleaning is a spray, soak and rinse job with a dry filter cleaner
• Same box, sleeve, inlets and elbow as the oiled 41890 kit

Hot intake air raises exhaust temperature, and on a loaded Super Duty that heat ends up in the transmission cooler too. If you tow, read our 6R140 overheating prevention guide and keep the fluid on schedule with the 6R140 filter and pan service guide.

How to confirm it is the right kit for your truck

Check the model year on the door jamb sticker and confirm the truck has the 6.7L diesel, not the gas engine. Look over the stock intake tube and turbo inlet for cracks or oil film before you start, and scan for stored codes so you have a baseline. If a transmission code shows up during that scan, sort it out first; our 6R140 limp mode causes guide helps separate a transmission fault from an engine air problem.

Fitment

Fits 2017, 2018 and 2019 Ford F250, F350 and F450 Super Duty pickups with the 6.7L Power Stroke. California Air Resources Board Executive Order D-161-132 covers both 41890 and 41890-D for 2017-2019 Ford trucks with the 6.7L diesel. The 2011-2016 trucks use a different Banks kit and 2020-up trucks use another, so the model year matters more than the cab or bed style. If your truck is a cab and chassis model, send us the VIN before ordering. Prefer an oiled element? The oiled filter version, 41890, uses the same hardware. Transmission parts for these trucks are in the 6R140 collection.

Install and filter care notes

• Plug the turbo inlet with a clean shop towel as soon as the stock tube comes off.
• The passenger battery and tray come out during the install and go back in their stock location afterward.
• Transfer the factory mass airflow sensor to the new box with the supplied screws and thread locker, keeping its original orientation.
• Snug the elbow clamps without crushing the rubber, and place the CARB label where the factory emissions decal was visible.
• To clean the dry element, Banks says to tap out loose dirt, spray a dry filter cleaner on both sides with most on the dirty side, soak 10 minutes, then rinse with cool or warm water from the clean side out until the water runs clear.
• Let it air dry. Never use gasoline, steam, strong detergents or a pressure washer, which can damage the media and harden the end caps.
• Banks gives a street service interval of 50,000 to 100,000 miles, sooner in heavy dust, or when a restriction gauge reads 18 inches of water.

To watch intake and exhaust temperature while towing, many owners pair this with the Banks Derringer tuner with iDash. A worn cooler line is a common leak point on these trucks, and our 6R140 cooler line kit replaces it.

What is the difference between the Banks 41890 and 41890-D?

The housing, inlets, sleeve and elbow are the same. The 41890 uses an oiled filter element and the 41890-D uses a dry element that is cleaned without filter oil.

Does the 41890-D fit a 2020 or newer F250?

No. It is for 2017-2019 Super Duty trucks with the 6.7L diesel only. 2020-up trucks need a different Banks Ram-Air kit.

Is the 41890-D street legal in California?

CARB Executive Order D-161-132 lists the 41890-D for 2017-2019 Ford trucks with the 6.7L diesel. Keep the CARB label on the truck where an inspector can see it.

How do I clean the dry filter?

Tap out loose dirt, spray a dry filter cleaner on both sides, let it soak about 10 minutes, rinse from the clean side out with cool or warm water, and let it air dry. Do not oil a dry element.

Do I need to relocate the battery or tune the truck?

No. The battery goes back in its factory location, and the stock mass airflow sensor keeps its original position, so no tune is required.

How often does the filter need service?

Banks lists 50,000 to 100,000 miles for street driving, sooner in dust or off road use, or when a restriction gauge reaches 18 inches of water.
