Dodge Ram Cummins oil-free intake details

aFe 51-31342-1 is the Magnum FORCE Stage-2 oil-free intake for qualified Dodge/Ram 2500 and 3500 6.7L Cummins applications from 2007.5 through 2012. A molded replacement tube and powder-coated heat shield use the retained lower original coupling, MAF, temperature sensor and filter minder.

Key Features

  • One 21-91044 Pro DRY S filter, three oil-free synthetic layers, 5-inch flange and 7.5-inch height.
  • Molded plastic tube 05-00897 and one-piece powder-coated heat shield 05-00898.
  • Separate supplied MAF and temperature-sensor gaskets; three #8-32 x 5/8-inch sensor screws.
  • Original lower coupling stays in place; the manual specifically avoids loosening the turbo connection.
  • 2010-plus mounting hardware is itemized separately; illustrated step says 2010 only, so confirm actual mounting arrangement.

Fitment

Current exact primary and linked manual specify 2007.5-2012 Ram 2500/3500 6.7L turbo diesel, correcting the old 2013 title endpoint. Confirm actual 2007.5 engine and production configuration rather than applying all 2007 engines. Two missing named rows are restored from exact selected-part tables: Dodge Ram 3500 SLT 2007-2010 and Ram 3500 Laramie 2011-2012. Original application bounds and gaps remain, including broader legacy SXT 2010. Exact retailer 4500/5500 positives conflict with the current manufacturer model scope and remain unextended pending housing/chassis proof; this is a source hold, not a physical incompatibility finding. Cab/chassis and pickup emissions eligibility must be assessed separately.

The shared bill offers one filter according to selected media, not three included filters. Extra dry filter, two gold restore kits and pre-filter belong only to the separate 75-series Value Pack. They are not contents of this selected dry kit. Generic oil-cleaning text is for alternate oiled media; keep this dry filter oil-free. The procedure uses original MAF, temperature sensor, filter minder, its grommet and lower coupler; new sensors, filter minder and a new lower coupling are not itemized. The procedure references a filter-minder grommet but the loose-parts bill does not separately list it. Inspect actual packaging and retain the original serviceable parts.

Frequently Asked Questions

What is the 51-31342-1?

One 21-91044 Pro DRY S oil-free filter with three synthetic layers, 5-inch flange and 7.5-inch height.

Does the original lower coupling stay?

Yes. Remove only the upper original intake tube and retain the lower coupler. The manual explicitly says not to loosen the turbo connection.

Which sensors transfer?

The original MAF and temperature sensor transfer with separate supplied gaskets; reconnect both harnesses.

Is a new filter minder included?

No separate new minder is itemized. The procedure transfers the filter minder and uses its grommet; confirm the actual serviceable original components.

What changes for later mounting?

The bill identifies 2010-plus bracket hardware, while step ten says 2010 only. Match the actual mounting arrangement before installing.

Are Value Pack cleaners and a second filter supplied?

Those extras are only listed for the separate 75-series Value Pack. This selected kit has one dry filter and requires dry-media cleaning.

Does the EO cover every listed pickup?

No. Reviewed D-550-26 includes this part for 2007-2009 pickup/cab chassis and 2010-2012 cab chassis; later pickup rows name other kits.

What torque or mileage check is specified?

The exact manual gives periodic clamp and hose checks, without numeric torque or mileage interval.

Installation Instructions

Verify aFe 51-31342-1. Read the complete one-page illustrated manual, all fifteen steps. Disconnect original MAF and temperature harnesses. Loosen clamps at the airbox and bottom of the upper tube, explicitly NOT at the turbo. Remove the upper tube while retaining the lower original coupler. Remove the front airbox nut and original assembly; retain the radiator bolt for reuse. Transfer original MAF and temperature sensor using supplied individual gaskets and sensor screws, then transfer filter minder and its grommet. Fit trim seal with cutout aligned at the housing pem-nut; mount tube to the outside of shield using specified hardware. Position assembly in original location. Use the appropriate additional mounting bracket: the bill labels it 2010-plus while step ten says 2010 only, so match actual mounting configuration. Ensure tube is fully inside retained original coupler before final tightening. Secure housing, restore original radiator bolt, tighten coupler clamp, reconnect both sensor harnesses and install selected filter. Check all joints and clearances; periodically inspect clamps and hoses. No mandatory battery disconnection, numeric torque or mileage recheck interval is given. Apply EO identification only after confirming exact vehicle and chassis eligibility.

Important Disclosures

Manufacturer advertises 81-percent more flow, 5 hp and 12 lb-ft. No linked flow or dyno sheet establishes baseline, pressure, selected-media run or test conditions, so those numbers remain manufacturer claims. Current primary says molded plastic tube and 18-gauge shield; retailer aluminum-tube and 16-gauge descriptions conflict and do not replace exact primary facts. Reviewed full D-550-26 Exhibit A explicitly includes the selected suffix part for 2007-2009 2500/3500 pickup and cab chassis, and 2010-2012 2500/3500 cab chassis. Other listed intake families cover later pickups; those rows do not certify this selected part for 2010-2012 pickups. Installation, application listing and emissions exemption are separate questions. Exact chassis, engine, kit configuration and EO conditions must match; label presence is not blanket certification.
