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

Banks 41890 is the oiled filter Ram-Air intake for 2017-2019 Ford F250, F350 and F450 Super Duty trucks with the 6.7L Power Stroke. It is built for owners who tow, want cooler exhaust temperatures and more filter capacity, and do not want an intake that forces them to relocate the battery. Banks rates it at a 40 percent air density increase at the turbo and a 49 percent mass airflow gain over the factory system.

What the Ram-Air intake does on a 2017-2019 Power Stroke

On these trucks the battery sits at the front corner of the engine bay, so air has to pass around it to reach the air box behind it. Banks spent its development work on keeping the box in the stock location behind the battery while still raising air density at the turbo inlet. The kit uses a forward facing inlet that ties into the factory opening, a secondary inlet that pulls the coolest available air, and a proprietary sleeve over the filter. The oiled element has 1,065 square inches of surface area, and Banks rates it at 99 percent filtration with high dirt capacity, so it goes more miles between cleanings. An EPDM rubber elbow with bellows connects the box to the turbo and includes a rest for the coolant hose.

Why owners upgrade the factory intake

• EGT rises quickly when towing a heavy trailer up long grades
• The stock filter clogs fast on dirt roads and needs frequent replacement
• You are adding a tuner or exhaust and want the intake to flow with them
• You want a washable filter instead of buying paper elements

Heat matters to the transmission too. A 6R140 working hard behind a hot engine is the one that cooks fluid first. Our 6R140 overheating prevention guide covers the cooling side, and the 6R140 limp mode causes guide helps separate a transmission fault from an engine airflow issue.

How to confirm the truck is ready for it

Check the model year and engine: this kit is only for the 2017-2019 body with the 6.7L diesel. Inspect the stock tube and turbo inlet coupler for oil residue or cracks, and pull codes before you start so you know what was already stored. If you are unsure which transmission your truck has, the 6R140 identification guide shows how to identify it.

Fitment

Fits 2017-2019 Ford F250, F350 and F450 Super Duty pickups with the 6.7L Power Stroke diesel. CARB Executive Order D-161-132 lists 41890 for 2017-2019 Ford trucks with the 6.7L diesel and notes the stock MAF sensor keeps its original location and orientation. 2011-2016 trucks use a different Banks kit, and 2020-up trucks use another, so match your model year. Cab and chassis trucks should be confirmed with your VIN. A dry filter version, 41890-D, is also available. Transmission parts for these trucks are in our 6R140 collection.

Install notes

• Cover the turbo inlet with a clean cloth as soon as the stock tube is off so nothing falls in.
• Release the four pressure clips and remove the factory intake and air box lid together, then remove the scoop and the battery tray, which is held by three bolts.
• Disconnect both negative terminals and the passenger side positive, then lift out the passenger battery with the fender covered.
• Move the MAF sensor to the Banks tube using the supplied screws with thread locker, and transfer the filter minder and grommet to the new lid.
• Hand start the tray and intake bolts so the assembly can be aligned, then tighten. Snug the two elbow clamps but do not over-tighten them.
• Place the CARB label on the radiator shroud, which is where Banks puts it.

Many owners add the Banks Derringer tuner with iDash to watch EGT and intake temperature, or the Monster exhaust to complete the airflow path.

Do I have to move the battery to install the Banks 41890?

No. You remove the passenger battery and tray during install, then put them back in the stock location. Banks designed the kit specifically to keep the factory battery position.

Is the 41890 legal in California?

Yes for 2017-2019 Ford trucks with the 6.7L diesel. It carries CARB Executive Order D-161-132; place the emissions label on the radiator shroud.

Will it fit my 2020 F250?

No. 2020-up Super Duty trucks use a different Banks Ram-Air kit. This one is for 2017-2019 only.

Do I need a tune?

No. The factory MAF sensor moves to the Banks tube in its stock orientation, and the CARB approval is based on the factory calibration.

How big is the filter?

Banks lists the oiled element at 1,065 square inches of surface area, the largest in its class, which is why it runs longer between cleanings.

Is there a dry filter option?

Yes. Banks sells the same kit as 41890-D with a dry element if you would rather not oil the filter.
