Silver Bullet spacer for exact engine and intake requirements
The aFe 46-35003 is a serrated/helix-entry 6061-T6 aluminum spacer for the listed 3.6L V6 Jeep and Dodge applications. Its two alternative screw sets have different tightening requirements; a single blanket torque is incorrect.
Key Features
- 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
- Match the new screw pattern to the original hardware. M6 x 50 mm screws use 10 Nm (89 in-lb); #12 x 2-inch screws use 5 Nm (44 in-lb). Do not interchange these torque values.
- The supplied gasket sits between the spacer and throttle body. Flat washers sit against the throttle body under the screw heads.
- The current exact page supports the factory intake and specifically names aFe 51-76214, 54-76214, 54-13035D and 54-13035R. This does not approve every unrelated aFe intake.
- The manufacturer advertises gains up to 6 hp and 14 lb-ft. These are test claims, not guaranteed results for every engine, intake and vehicle.
Fitment
| Years / source scope | Model | Exact requirements |
|---|---|---|
| 2012–2018 | Jeep Wrangler JK | 3.6L V6; distinguish JK from the concurrent 2018 JL |
| 2011–2021 | Jeep Grand Cherokee | 3.6L V6 |
| 2011–2024 manual / through 2026 current headline | Dodge Durango | 3.6L V6; later-year hardware details need exact confirmation |
46-35003: The exact current manual lists JK, Grand Cherokee and Durango 3.6L engines. The current Durango headline extends to 2026 while the linked instructions stop at 2024; no new named later trims are invented. Existing named trims remain conditional on the actual V6 and compatible intake. An older EO exhibit lists additional car applications, but those are not added because the current manual does not establish their installation.

Frequently Asked Questions
What is the 46-35003?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 between spacer and throttle body; flat washers against throttle body.
What is the correct torque?M6 x 50 mm:10 Nm (89 in-lb); #12 x 2-inch:5 Nm (44 in-lb). Match actual factory threads.
Are all original search rows certified?The exact current manual lists JK, Grand Cherokee and Durango 3.6L engines. The current Durango headline extends to 2026 while the linked instructions stop at 2024; no new named later trims are invented. Existing named trims remain conditional on the actual V6 and compatible intake. An older EO exhibit lists additional car applications, but those are not added because the current manual does not establish their installation.
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 current page cites D-550-41. The 2019 exhibit lists narrower earlier scopes for some models; it does not certify every later year in today’s manual/headline. Match the exact applicable exemption and retain the required identification label.
Installation Instructions
- Read the exact manufacturer instructions for 46-35003, verify the actual engine, intake, hardware and applicable emissions scope before removal.
- The manual illustrates the JK. Remove the engine cover and intake tube as appropriate to the actual application, including the front retaining screws and the temperature-sensor connector below the tube.
- Remove the throttle-body fasteners, saving them for possible restoration. Compare the original threads with the two supplied screw sets before fitting the spacer.
- Install the supplied gasket between spacer and throttle body, and place the flat washers against the throttle body. Use only the correctly matched four screws.
- Tighten M6 x 50 mm screws to 10 Nm (89 in-lb), or #12 x 2-inch screws to 5 Nm (44 in-lb), as identified in the exact manual. Do not apply one torque to both thread types.
- Restore the intake, temperature-sensor connection and engine cover, check all connections, and recheck screws and clamps after 100 miles.
46-35003: installation details and any unresolved source scope must be matched to the actual vehicle before use.
