Silver Bullet spacer for exact engine and intake requirements

The aFe 46-37004 black Silver Bullet spacer is for the listed Honda/Acura 3.5L V6 applications. It includes a gasket and hardware for the original throttle body, not a replacement throttle body or full intake.

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 black anodized finish and serrated/helix entry.
  • The exact manual supports Takeda 56-70016R/D and 56-70013R/D. Proper fit is not guaranteed with other aftermarket intake systems.
  • Manufacturer power, response and whistle statements are claims, not guaranteed improvements.

Fitment

Years / source scope Model Exact requirements
2014–2020 Acura MDX / RLX 3.5L V6; exact engine/version required
2015–2020 Acura TLX 3.5L V6 only; not four-cylinder
2013–2018 Acura RDX 3.5L V6
2016–2024 linked manual Honda Pilot 3.5L V6

2017–2026 current page; manual through 2024 Honda Ridgeline 3.5L V6

46-37004: The linked exact manual documents all seven model families above. The current page extends Ridgeline through 2026, whereas its manual ends at 2024; that difference is qualified rather than copied to the other Honda models. New broad year coverage uses model-level entries and does not certify every named trim, hybrid or engine revision. Existing Acura rows remain conditional on the exact 3.5L engine; no Sport Hybrid compatibility is inferred.

Frequently Asked Questions

What is the 46-37004?

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?

The exact parts list below governs. Generic manufacturer page fields do not establish a supplied intake filter or coupling for this spacer.

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?

Place the supplied gasket between spacer and throttle body, with AIR IN toward the throttle body.

What is the correct torque?

The exact manual specifies 15 ft-lb for the supplied M8 x 80mm screws.

Are all original search rows certified?

The linked exact manual documents all seven model families above. The current page extends Ridgeline through 2026, whereas its manual ends at 2024; that difference is qualified rather than copied to the other Honda models. New broad year coverage uses model-level entries and does not certify every named trim, hybrid or engine revision. Existing Acura rows remain conditional on the exact 3.5L engine; no Sport Hybrid compatibility is inferred.

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 page cites D-550-47 and excludes FHNXV03.5VK2, GHNXV03.5PK3, EHNXV03.52G2, JHNXV03.5BK3, KHNXV03.5FL3 and HHNXV03.5LK3. Match the actual underhood test group. The full official order could not be independently read, so remaining model-year/test-group exemption is not fully certified.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-37004, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Remove the engine cover, disconnect the crankcase hose, loosen the body/airbox clamps and remove the intake tube.
  3. Remove the two throttle-body screws and two nuts. Remove the manifold studs using the exact manual's double-nut method.
  4. Position the spacer and gasket between manifold and throttle body with AIR IN toward the body and gasket on the throttle-body side.
  5. Install the four supplied M8 x 80mm screws with lock washers and flat washers. Tighten to 15 ft-lb.
  6. Restore the tube and engine cover, reconnect the crankcase hose and tighten all clamps. Confirm the installed intake is supported.
  7. Recheck bolts and clamps after 100 miles. Compare the actual underhood test group to the listed exclusions and confirm the applicable EO before use.

46-37004: installation details and any unresolved source scope must be matched to the actual vehicle before use.
