aFe 51-76104 is the Momentum GT intake with one selected Pro DRY S filter. Its exact manufacturer installation manual specifies 2010–2016 Nissan Patrol Y62 with the 5.6L VK56DE V8 and a 320-hp application label; existing QX80 coverage is separately qualified against the official executive-order exhibit and exact-part retailer tables.
The exact manual names 2010–2016 Patrol Y62, 5.6L VK56DE V8, with a 320-hp application label. That output is an identification condition, not an invented trim. Existing 2014–2017 INFINITI QX80 and 2016–2017 Limited rows are retained: official CARB order D-550-25 Exhibit A explicitly lists this intake for 2014–2017 QX80 and 2010–2015 Armada, and exact-part retailer tables also list the existing QX80 rows. Those positives differ from the manual’s VK56DE Patrol installation scope, so matching actual engine variant, MAF, both CCV connections, throttle-body position and housing mounts remains required. The order is not blanket physical-fit approval of every related vehicle or engine. No Armada row, later Patrol year or additional trim is added solely from that exhibit; supplied-revision and source-scope conflicts remain qualified.

Use the exact illustrated housing/filter mating surfaces and large T-bolt arrangement; the manual says clamp appearance may vary. It also refers to a filter-flange clamp in assembly without a separate numbered service row. Reuse original MAF screws rather than borrowing M4 screws from the other Patrol kits. Transfer three original steel sleeves and rubber grommets and all three original housing bolts. Transfer the original rubber duckbill drain only when equipped; the manual directs leaving that location open otherwise. Both original CCV hoses and engine-cover bolts are reused. No numeric filter-layer count or current exact dyno/flow gain is certified from the unavailable current product page.
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 21-91061 selected Pro DRY S filter; the shared manual’s other media rows are alternatives.
Is Pro DRY S oiled?No. Use the correct dry-filter service method; do not oil it.
Is a new MAF sensor supplied?No. Transfer the original sensor using its original screws.
Which mounting hardware is used?Three original housing sleeves and grommets with three retained housing bolts.
Is a pre-filter supplied?No pre-filter is listed in this exact manual; do not borrow the other Patrol kit’s contents.
Are the original vent connections retained?Reconnect both original CCV hoses to the new tube.
Does another Patrol engine establish compatibility?No. Match the exact engine, generation, original connections, mounting layout and source qualifications for this selected kit.
What torque and inspection interval does the manual specify?No numeric torque. Check connections after 100–200 miles.
Verify aFe 51-76104. Read the full exact manual on a cool engine and disconnect the negative battery terminal as directed. Retain the two engine-cover bolts and remove the cover. Disconnect MAF, release its housing harness clip and retain the three housing bolts. Disconnect both CCV hoses from the resonance chamber and loosen the throttle-body clamp, then lift out the intake assembly. Place the large T-bolt over the new housing flange. Clean the inside housing flange and both filter mating surfaces as directed, then fit the filter and tube and tighten their clamps. Assemble the reducing elbow and two smaller clamps. Transfer the original MAF using its original screws. Transfer all three original steel sleeves and rubber grommets, plus the original duckbill drain if equipped. Fit the elbow over the throttle body, rotate the assembly clockwise to align its three mounts, restore all three original housing bolts and tighten the throttle-body clamp. Reconnect MAF and both CCV hoses, secure the harness safely with the supplied ties and restore the engine cover with its original bolts. Verify all connections and follow the vehicle procedure for battery reconnection. No numeric torque is provided. Recheck connections after 100–200 miles.
The exact manufacturer manual’s California race-only wording applies to its named Patrol installation scope, while the separate official D-550-25 exhibit lists this intake for specified QX80/Armada years. Preserve that distinction: an executive order covers only its listed applications and conditions, not every engine, later year, non-US Patrol or modified configuration, and does not resolve the manual’s engine/layout conflict. Existing EO tags are retained without expanding their scope. The current exact manufacturer product page and current exact flow/dyno files were not located; no numeric horsepower, torque, airflow or filter-layer claim is borrowed from a related intake. The full primary installation manual remains the source for its listed contents and procedure.
