aFe 51-76105 is the Momentum HD intake for Nissan Titan XD 5.0L Cummins diesel, with one selected 21-91059 Pro DRY S filter. The exact shared manufacturer-authored manual identifies both media options and covers 2016-2019. Three oil-free synthetic layers, molded housing and tube, a silicone elbow and three T-bolt clamps make up the selected dry configuration. Both original MAF and temperature sensors transfer; the external scoop is separate.
The five existing Titan XD Platinum Reserve, PRO-4X, S, SL and SV 2016-2019 ranges remain unchanged and require the 5.0L Cummins diesel. The exact shared manual covers 2016-2019. No 5.6L gasoline XD or non-XD Titan application is inferred. The manufacturer guide contains conflicting 5.6L header text but its Cummins section and exact manual identify 5.0L diesel. Physical fitment does not establish emissions exemption: the reviewed D-550-26 exhibit names 51-76105-E rather than this nonsuffix part, and only 2016-2017.

Retain the original MAF sensor, temperature sensor, three rubber isolation mounts and firewall-side housing bolt. The exact bill does not include an external scoop, new breather fitting, sensor extension or tuning module. Generic retailer aluminum-breather-fitting wording is not certified by the exact diesel bill or procedure.
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
One 21-91059 Pro DRY S oil-free filter. The shared bill also shows the alternative Pro 10R element, which is a separate media choice.
Does the existing EO number establish this entire application?The reviewed exhibit names 51-76105-E for 2016-2017, not this nonsuffix part or 2018-2019. Exact-version equivalence and later coverage remain unestablished.
How many sensor screws are supplied?Three M4 x 0.7 x 8 mm screws transfer both original MAF and temperature sensors.
Which original mounting parts remain?Transfer all three rubber isolation mounts and reuse the firewall-side housing bolt.
Does the kit include an external scoop?The external scoop is sold separately. The intake includes a plug for its auxiliary housing opening.
Is a new breather fitting listed?No new breather fitting is itemized in the exact bill or transfer procedure, despite generic retailer wording.
Is the dry intake documented as a 20-percent flow improvement?The manufacturer guide lists dry flow gain as TBD. Its 20-percent figure belongs to the separate oiled version; no selected dry comparison chart was verified.
What torque and mileage recheck are given?The exact manual states neither numeric torque nor a mileage recheck interval. Verify all connections are secure.
Verify aFe 51-76105. Read all sixteen pages and figures A-H. Work on a cool engine and disconnect the negative battery terminals as directed. Disconnect MAF and temperature harnesses, loosen the turbo-inlet clamp, release the two airbox spring clips and remove the upper housing and tube. Remove the flat filter, retain the firewall-side 10 mm housing bolt and remove the lower housing and original fender intake duct. Transfer three rubber isolation mounts to the new housing. Fit its large clamp loosely, push the housing onto the two lower studs and secure it with the original bolt. Insert the selected filter with clamps loose. Transfer the original MAF and temperature sensors to the new tube using the three supplied M4 x 0.7 x 8 screws. Fit the 90-degree elbow and clamps loosely to the turbo inlet, insert the tube into that coupling first and then the filter, align the assembly and secure all clamps. Reconnect both sensor harnesses. Install an optional separately purchased scoop only according to its own manual; otherwise choose whether to close the auxiliary opening with the supplied plug. Verify secure connections. For an actually covered exempt configuration, follow the manual instruction to place the supplied EO label on a clean, smooth surface on or near the intake. The exact manual gives no numeric torque or mileage interval.
A current exact nonsuffix manufacturer product page was not located. The manufacturer-authored shared sixteen-page manual explicitly identifies this dry part, and all four contacts, complete bill and figures A-H were read and viewed. The manufacturer 2019 application guide printed page 151 identifies the exact dry part and 21-91059 element, lists its flow gain as TBD and advertises 9 hp / 15 lb-ft. The exact dry retailer corroborates three synthetic layers but its 99.2-percent efficiency report was not supplied; no independent efficiency certification is made. No selected dry comparison chart or run sheet was verified, so the separate Pro 10R flow and dyno are not dry certification. The guide also mislabels the oiled row Pro 5R while naming the Pro 10R service filter and has a conflicting 5.6L header; the exact shared manual establishes 5.0L diesel. The reviewed official D-550-26 text and rendered exhibit identify 51-76105-E for Titan XD 5.0L turbo 2016-2017. This does not prove equivalence to the nonsuffix part, later-year exemption or separate external-scoop exemption. Existing EO metadata is retained with this unresolved exact-version qualification. Confirm actual part identification, applicable order conditions and emissions-label requirements.
