The aFe 46-36004 Silver Bullet spacer fits the listed later Nissan/Infiniti 5.6L applications. Unlike the other spacers in this family, it includes a flexible coupling for the supported aFe intake installation.

46-36004: The exact manual supports the listed Armada/QX years but lists Patrol only for 2010β2013 with the 400-hp 5.6L. The current page's broader Patrol Y62 2010β2026 range is qualified; only the narrower documented 2010β2013 Patrol scope is newly mapped. Later Armada/QX80 coverage is added at model level without invented trim names. The page's V9 engine typo in a dyno sentence is not a nine-cylinder specification.
| Detail | Value |
|---|---|
| Manufacturer Part Number | 46-36004 |
| Material / design | 6061-T6 billet aluminum; serrated/helix entry |
| Engine / application | See exact engine-specific fitment table and source qualifications |
| Sealing arrangement | Keep the original manifold O-ring seated and undamaged. Put the supplied gasket between spacer and body, engraved spacer side toward the throttle body. |
| Throttle-body fastening | The exact manual specifies 89 in-lb for the throttle-body assembly, using a lock washer next to the screw head and flat washer next to the body. |
| Emissions scope | The read D-550-40 lists QX56 2011β2013, QX80 2014β2019 and Armada 2017β2019. It does not establish Patrol or later-year exemption. Confirm exact coverage and required labeling rather than treating the broader product headline as blanket legality. |
aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
A model- and engine-specific Silver Bullet throttle-body spacer, not a complete intake or replacement throttle body.
Does it include a filter or coupling?Yes, one flexible coupling is listed for the supported aFe intake installation, plus two T-bolt clamps for use only if needed. No filter or complete intake is listed.
Are gains guaranteed?No. Turbulence, throttle-response and whistle statements are manufacturer design claims, not guaranteed horsepower, fuel-economy or sound results for the actual engine.
Which sealing parts are used?Keep the original manifold O-ring seated and undamaged. Put the supplied gasket between spacer and body, engraved spacer side toward the throttle body.
What is the correct torque?The exact manual specifies 89 in-lb for the throttle-body assembly, using a lock washer next to the screw head and flat washer next to the body.
Are all original search rows certified?The exact manual supports the listed Armada/QX years but lists Patrol only for 2010β2013 with the 400-hp 5.6L. The current page's broader Patrol Y62 2010β2026 range is qualified; only the narrower documented 2010β2013 Patrol scope is newly mapped. Later Armada/QX80 coverage is added at model level without invented trim names. The page's V9 engine typo in a dyno sentence is not a nine-cylinder specification.
Can another spacerβs instructions be substituted?No. Gaskets, O-rings, brackets, screw sizes, control cables and intake restrictions differ by exact part number.
Does the EO reference cover every application?The read D-550-40 lists QX56 2011β2013, QX80 2014β2019 and Armada 2017β2019. It does not establish Patrol or later-year exemption. Confirm exact coverage and required labeling rather than treating the broader product headline as blanket legality.
46-36004: installation details and any unresolved source scope must be matched to the actual vehicle before use.

The selection includes BBK, FAST, Granatelli, aFe, BLOX, APR, Dinan, Banks and other application-specific references.Throttle Bodies and Control LayoutElectronic bodies need compatible wiring, pedal and engine-management support, while cable bodies require the correct linkage, idle-control and sensor arrangement. Match the complete application rather than assuming every throttle body for an engine family uses the same control method.Compare bore layout, manifold pattern and inlet connection with the actual intake system. A larger opening alone does not establish more power; airflow needs, control compatibility and the rest of the engine combination matter.Spacers, Adapters and Intake ConnectionsA spacer adds a defined section between compatible components.

Compare bore shape, bolt pattern, thickness and the seals or hardware included. Some references require a particular aftermarket intake rather than every intake on the same vehicle.Check hood and engine-bay clearance, intake-tube position and any linkage or wiring reach after adding thickness. Product-specific design data is more useful than a universal horsepower or fuel-economy claim.Adapters and CouplersTorque Solution Subaru references distinguish specific manifold and throttle-body combinations, including named DBC-to-DBW-manifold arrangements.
