Silver Bullet spacer for exact engine and intake requirements

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.

Key Features

  • 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
  • 6061-T6 billet aluminum with serrated/helix entry.
  • Supports factory intake or aFe 51/54/75-76103 installations using their distinct manual procedures. Explicitly does not fit aFe 51/54/75-76104.
  • Replace the supported aFe intake's rigid coupling with the supplied flexible coupling; do not assume that coupling is required for the factory-intake route.
  • Manufacturer dyno/power claims do not guarantee gains; nominal silicone-material claims do not supply an unverified numeric temperature or pressure rating.

46-36004: The exact manual supports the listed Armada/QX years but lists Patrol only for 2010–2013 with the 400-hp 5.6L. The current page's broader Patrol Y62 2010–2026 range is qualified; only the narrower documented 2010–2013 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.

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 2011–2013, QX80 2014–2019 and Armada 2017–2019. 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.

Frequently Asked Questions

What is the 46-36004?

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 2010–2013 with the 400-hp 5.6L. The current page's broader Patrol Y62 2010–2026 range is qualified; only the narrower documented 2010–2013 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 spacer’s 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 2011–2013, QX80 2014–2019 and Armada 2017–2019. 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.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-36004, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Remove the engine cover's two bolts, disconnect the MAF harness and loosen the body clamp. Unclip the airbox upper section, loosen the resonator clamp and move the resonator aside as instructed.
  3. Remove and retain the four factory throttle-body bolts; they are not reused for this installation.
  4. For the factory intake, position the spacer and gasket with engraved side toward the body, gasket on body side, and original manifold O-ring retained.
  5. For a supported 51/54/75-76103 aFe intake, replace its more rigid coupling with the supplied flexible coupling, then fit the spacer/gasket with the same original O-ring arrangement. Do not use this kit with 51/54/75-76104.
  6. Install the supplied screws with lock washers against the heads and flat washers toward the body. Tighten the assembly to 89 in-lb. Use the extra T-bolt clamps only if needed.
  7. Restore the airbox upper section, tube, resonator, clamps, MAF harness and engine cover with original bolts. Check secure connections and exact EO labeling.

46-36004: installation details and any unresolved source scope must be matched to the actual vehicle before use.
