Silver Bullet spacer for exact engine and intake requirements
The aFe 46-33016 is the 2011–2014 Mustang/F-150 3.7L V6 spacer. Its short supplied hose reconnects the breather; it is not an intake coupling or approval for a different engine.
Key Features
- 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
- Exact instructions replace the rubber section of the breather connection with the supplied short hose and clamps.
- The manual provides no numeric throttle-body fastening torque; a value from another spacer is not substituted.
- Generic page filter/coupling fields do not override the exact kit list.
Fitment
| Years / source scope | Model | Exact requirements |

| 2011–2014 exact page / manual | Ford Mustang | V6 3.7L |
| 2011–2014 exact page / manual | Ford F-150 | V6 3.7L |
46-33016: The exact manufacturer page and manual agree on the 2011–2014 3.7L V6 applications. Existing broad model rows remain conditional on that engine; Base is not used as an invented engine trim. No 3.5L EcoBoost, 5.0L or later model application is inferred.
Specifications

| Engine / application | See exact engine-specific fitment table and source qualifications |
| Sealing arrangement | One supplied gasket between spacer and throttle body; AIR IN faces outward. |
| Throttle-body fastening | No numeric throttle-body torque is specified in the exact manual. Obtain the correct assembly specification rather than borrowing another spacer’s value. |
| Emissions scope | The exact current page states this part is not CARB exempt and gives California purchase/use restrictions. D-550-43 entries for another part number and a 3.7L engine do not certify this kit. |

Frequently Asked Questions
What is the 46-33016?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; AIR IN faces outward.
What is the correct torque?No numeric throttle-body torque is specified in the exact manual. Obtain the correct assembly specification rather than borrowing another spacer’s value.
Are all original search rows certified?The exact manufacturer page and manual agree on the 2011–2014 3.7L V6 applications. Existing broad model rows remain conditional on that engine; Base is not used as an invented engine trim. No 3.5L EcoBoost, 5.0L or later model application 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 exact current page states this part is not CARB exempt and gives California purchase/use restrictions. D-550-43 entries for another part number and a 3.7L engine do not certify this kit.
Installation Instructions
- Read the exact manufacturer instructions for 46-33016, verify the actual engine, intake, hardware and applicable emissions scope before removal.
- Disconnect the breather hose from the inlet tube, loosen the tube clamps and remove the tube. Remove the original rubber breather section and its clamps.
- Unbolt the throttle body. Position the spacer with AIR IN outward and place the supplied gasket between spacer and throttle body.
- Secure with the supplied longer bolts and flat washers using the correct specification for the actual assembly; no numeric torque is supplied in this exact manual.
- Use the supplied hose and clamps to reconnect the breather to the inlet tube. Reinstall the tube, tighten its clamps, reconnect the breather and inspect every connection.
46-33016: installation details and any unresolved source scope must be matched to the actual vehicle before use.
