aFe Ram 2500/3500 6.4L Pro DRY S Stage-2 Intake

Ram 6.4L HEMI Stage-2 intake details

aFe 54-13047D is a Magnum FORCE Stage-2 open-element intake for the qualified Ram 2500/3500 6.4L HEMI gasoline applications below. It pairs one Pro DRY S filter with an XLPE housing and tube while retaining the factory inlet scoop, three housing mounting grommets and intake-air-temperature sensor. The modified crankcase-ventilation line retains the original elbow.

Key Features

• One nine-inch-tall inverted-top Pro DRY S filter with a five-inch round flange; three oil-free synthetic layers.
• Heat-resistant XLPE polymer tube and open-element housing.
• Retains the factory inlet scoop and three original housing mounting grommets.
• Transfers the original intake-air-temperature sensor into the supplied fitting and rubber grommet.
• Silicone reducer uses a size 056 throttle-side clamp and size 060 tube-side clamp.
• Selected-media measured bench flow: 565 versus stock 430 CFM at 7 inches H2O; calculated 31.40% increase.

Fitment

Current exact manufacturer page covers 2019-2026 Ram 2500/3500 V8-6.4L HEMI; its linked illustrated manual explicitly lists 2019-2025 Ram 2500, 2500 Power Wagon and 3500. Exact selected-part retailer tables support the named ranges below, including shorter Laramie Longhorn, Lone Star and SLT bounds. These are gasoline-engine-qualified rows, not permission for Cummins diesel or every powertrain sold under the same trim. Original coverage is retained; no drivetrain or engine is invented as a trim.

Verify 54-13047D against the actual engine, sensor and vent connections, mounting locations and applicable emissions requirements before ordering.

Specifications

What's Included

The two filter entries in the shared bill are media alternatives: this selection supplies one filter. The bill lists the hose quantity as 24 but describes a 26-inch-long piece on that same line; its illustration shows one hose. Confirm actual supplied length rather than claiming 24 hoses or resolving the discrepancy by assumption. Transfer the original CCV elbow, intake-air-temperature sensor, three housing grommets and inlet scoop, and reinstall the engine cover. The filter flange clamp is separate from the two supplied coupling clamps; no new sensor, wiring harness, housing mounting grommets or sensor screws are itemized.

Frequently Asked Questions

The qualified Ram 2500/3500 6.4L HEMI gasoline application, including the named Power Wagon rows. It is not a Cummins diesel intake.

One 21-91120 Pro DRY S filter. The manual lists the other media as an alternative, not a second included element.

Retain the factory inlet scoop, three housing mounting grommets, intake-air-temperature sensor, CCV elbow and engine cover.

No. The illustrated procedure transfers the original intake-air-temperature sensor into the supplied fitting and rubber grommet; no new MAF sensor is listed.

Put the smaller end on the throttle body with the size 056 clamp. Leave the size 060 clamp on the tube end loose until the tube is aligned.

Transfer the original elbow to the supplied hose using the coupling fitting. Put the elbow on the crankcase port and route the hose underneath the smaller vacuum line to the intake-tube port.

The manual cover ends at 2025; the current exact manufacturer page extends the 6.4L application to 2026. Named rows use selected-part retailer evidence and remain engine-qualified.

No numeric clamp torque or battery step is supplied. Recheck screws, clamps and connectors after 100-200 miles. The marked dyno gains and peak-to-peak differences are distinct; different-day results are not guaranteed.

Installation Instructions

Verify aFe 54-13047D. Read the complete manual and work on a cool engine. Lift the engine-cover front edge, pull forward and retain it. Loosen the throttle-body and housing clamps, disconnect the temperature sensor, unclip its wire, disconnect the CCV hose and remove the intake tube. Remove the six original lid screws, lid and stock filter. Release the original inlet duct from the stock housing/scoop while keeping it in the vehicle, then lift the lower housing from its grommets. Transfer the three stock grommets to the new housing; lower it into position, insert the original inlet scoop and press onto all three mounts. Install and trim the housing-edge seal. Remove the stock CCV line, insert the supplied coupling fitting into the silicone hose and transfer the original elbow. Fit the rubber grommet and temperature-sensor fitting into the new tube; a small amount of silicone grease may ease fitting insertion. Transfer the original temperature sensor. Remove the filter flange clamp, lower the filter through the top of the housing and snap its base into place, then refit its clamp. Put the smaller reducer end on the throttle body with the size 056 clamp and tighten; leave the size 060 tube-side clamp loose. Slide the tube into the throttle-body coupling FIRST, rotate its large end into the filter, align and tighten all clamps. Reconnect the modified CCV hose with the original elbow at the crankcase port and the hose routed underneath the smaller vacuum line, then reconnect the temperature-sensor harness and reinstall the engine cover. Check everything is secure and recheck screws, clamps and connectors after 100-200 miles. No battery step, new MAF sensor or numeric clamp torque is prescribed.

Important Disclosures

Both own linked 20-page manuals were fully read and all five contact sheets for each were visually inspected, including the complete bill and Figures A-P. They have identical extracted text but different file hashes; each was inspected separately. The selected flow and dyno sheets were also visually inspected. At the marked 4,697 rpm, 337.19/311.59 HP and 377.09/348.44 lb-ft differ by 25.60 HP and 28.65 lb-ft. Legend maxima instead differ by 15.70 HP and 33.95 lb-ft (361.56/345.86 HP; 382.39/348.44 lb-ft). The selected intake run was February 27, 2020, SAE 0.99, versus the February 26 stock-intake baseline, SAE 1.01. Notes identify fourth gear, Tow/Haul on and 20% preload; RPM is not connected and exact vehicle/exhaust details are not printed. These different-day results do not guarantee the same gains on every vehicle. The hose quantity/length discrepancy remains qualified. Turn14 exact-product information requires unavailable authenticated access. No fixed filter-cleaning mileage, guaranteed output, CARB exemption or price change is claimed.
