The aFe 46-38011 Silver Bullet spacer is for the listed 4.0L Toyota applications. The current fitment note specifically supports aFe intake families 51/54/75-76009 and 51/54/75-76010. It retains the original throttle body.
| Years / source scope | Model | Exact requirements |
|---|---|---|
| 2010–2024 | Toyota 4Runner (US) | 4.0L V6; confirm installed intake |
| 2010–2014 | Toyota FJ Cruiser (US) | 4.0L V6; confirm installed intake |
| 2015–2023 | Toyota FJ Cruiser (non-US) | 4.0L V6; separate regional coverage |
| 2015–2022 | Toyota Land Cruiser (non-US) | 4.0L V6 only; not US V8 |
| 2015–2023 | Toyota Land Cruiser Prado (non-US) | 4.0L V6 only |
46-38011: The exact manuals start 4Runner coverage at 2010, not 2003. Unsupported earlier rows have been removed. Non-US FJ Cruiser and Land Cruiser/Prado applications are separately identified and are not US-market extensions. Current manufacturer 4Runner coverage reaches 2024. Named trim rows remain conditional on the 4.0L engine and correct intake; later 2022–2024 coverage uses a model-level entry without invented trim detail.
| Detail | Value |
|---|---|
| Manufacturer Part Number | 46-38011 |
| Material / design | 6061-T6 billet aluminum; serrated/helix entry |
| Engine / application | See exact engine-specific fitment table and source qualifications |
| Sealing arrangement | The supplied flat gasket sits between spacer and throttle body. AIR IN faces the throttle body, away from the manifold. |
| Throttle-body fastening | The exact manual gives no numeric torque. Do not borrow the other spacer's 10 Nm value; use the correct factory requirement and exact instructions. |
| Emissions scope | The page references CARB EO D-550-42 for some or all applications, and the manual lists an EO sticker. The complete EO table could not be independently read because access presented a verification challenge. Verify the exact application and label requirements; not all US or non-US rows are certified exempt. |

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?The supplied flat gasket sits between spacer and throttle body. AIR IN faces the throttle body, away from the manifold.
What is the correct torque?The exact manual gives no numeric torque. Do not borrow the other spacer's 10 Nm value; use the correct factory requirement and exact instructions.
Are all original search rows certified?The exact manuals start 4Runner coverage at 2010, not 2003. Unsupported earlier rows have been removed. Non-US FJ Cruiser and Land Cruiser/Prado applications are separately identified and are not US-market extensions. Current manufacturer 4Runner coverage reaches 2024. Named trim rows remain conditional on the 4.0L engine and correct intake; later 2022–2024 coverage uses a model-level entry without invented trim detail.
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 references CARB EO D-550-42 for some or all applications, and the manual lists an EO sticker. The complete EO table could not be independently read because access presented a verification challenge. Verify the exact application and label requirements; not all US or non-US rows are certified exempt.
46-38011: installation details and any unresolved source scope must be matched to the actual vehicle before use.

Choose throttle hardware and pedal-response electronics by the job they perform. Compare complete throttle bodies, manifold adapters, spacers and electronic controllers for the engine and control system installed. 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.
