Silver Bullet spacer for exact engine and intake requirements

The aFe 46-38002 Silver Bullet spacer is for the listed Toyota 4.0L V6 applications. Supplied offset brackets reposition the air-cleaner assembly; this kit is distinct from the later Toyota spacer.

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.
  • Includes air-cleaner offset brackets and their countersunk screws.
  • Manufacturer airflow, response and power statements are claims rather than guaranteed results.

Fitment

Years / source scope Model Exact requirements
2005–2009 Toyota 4Runner 4.0L V6; not 2003–2004
2007–2009 Toyota FJ Cruiser 4.0L V6
2005–2015 Toyota Tacoma 4.0L V6
2005–2012 manual; EO through 2013 Toyota Tundra 4.0L V6 only; 2013 source conflict remains

46-38002: The exact manual starts 4Runner coverage at 2005, so earlier 2003–2004 portions of existing rows are removed. It lists Tundra through 2012, while EO D-550-17 lists 2013. The existing 2013 Tundra portion remains a source-conflict hold, not a certified installation or a claim of physical incompatibility. The unsupported 2014 Tundra SR group is removed. All named trim rows still require the actual 4.0L engine; V8 and four-cylinder vehicles are not included by a shared trim name.

Frequently Asked Questions

What is the 46-38002?

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?

One supplied gasket sits between spacer and throttle body, with AIR IN facing the throttle body.

What is the correct torque?

The exact manual specifies 10 Nm (89 in-lb) for the throttle-body bolts. No numeric offset-bracket torque is published there.

Are all original search rows certified?

The exact manual starts 4Runner coverage at 2005, so earlier 2003–2004 portions of existing rows are removed. It lists Tundra through 2012, while EO D-550-17 lists 2013. The existing 2013 Tundra portion remains a source-conflict hold, not a certified installation or a claim of physical incompatibility. The unsupported 2014 Tundra SR group is removed. All named trim rows still require the actual 4.0L engine; V8 and four-cylinder vehicles are not included by a shared trim name.

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-550-11 / D-550-17. The read D-550-17 has application-specific coverage and conditions; its Tundra 2013 listing differs from the mechanical manual. Exemption does not prove every installation or performance claim.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-38002, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Remove the engine cover and air inlet tube, unlatch and remove the filter, then disconnect the vacuum line, PCV vent hose and MAF connector. Remove air-cleaner mounting bolts and assembly.
  3. Disconnect the throttle-body harness and remove its bolts. Install the spacer, supplied gasket and body with AIR IN toward the throttle body.
  4. Use the supplied 6mm x 75mm bolts and flat washers; tighten the throttle-body assembly to 10 Nm (89 in-lb). Reconnect its harness.
  5. Install both offset brackets at the air-cleaner mounting points with the countersunk screws, then align and reinstall the air-cleaner assembly and inlet tube.
  6. Restore the MAF connector, PCV hose, vacuum line, filter and clamps. The manual allows leaving the engine cover off or securing it with the one nut as described; check connections and exact EO labeling.

46-38002: installation details and any unresolved source scope must be matched to the actual vehicle before use.
