The aFe 46-33017 is documented for the 2011–2016 F-150 3.5L twin-turbo EcoBoost installation. It is not a blanket approval for every engine listed under an emissions-family table.
| Years / source scope | Model | Exact requirements |
|---|---|---|
| 2011–2016 exact page / manual | Ford F-150 EcoBoost | V6 3.5L twin-turbo; match the installed cold-side charge tube |
46-33017: The exact current page/manual agree on 2011–2016 3.5L twin-turbo F-150. D-550-43 additionally lists other engine rows under this part number, but those rows are not used to extend its mechanical application beyond the exact current page/manual. The page’s BladeRunner cold-side restriction is printed as 2005–2016; that wording is retained as a tube-compatibility warning, not a new 2005 EcoBoost vehicle application.
| Detail | Value |

aFe Power develops application-specific intake, filtration, exhaust, cooling, tuning, suspension, drivetrain, and truck-performance components supported by product testing and documented installation requirements.
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 in the spacer/throttle-body arrangement; AIR IN faces the throttle body.
What is the correct torque?Throttle-body bolts: 10 Nm (89 in-lb), with bolts and clamps rechecked after 100 miles.
Are all original search rows certified?The exact current page/manual agree on 2011–2016 3.5L twin-turbo F-150. D-550-43 additionally lists other engine rows under this part number, but those rows are not used to extend its mechanical application beyond the exact current page/manual. The page’s BladeRunner cold-side restriction is printed as 2005–2016; that wording is retained as a tube-compatibility warning, not a new 2005 EcoBoost vehicle application.
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?Inspected D-550-43 includes the exact 2011–2016 3.5L turbocharged F-150 scope plus other engine rows. Those additional EO rows do not override narrower mechanical instructions or charge-tube restrictions.
46-33017: installation details and any unresolved source scope must be matched to the actual vehicle before use.

Compare ICON suspension systems, Bilstein or Fox shocks, engine-specific airflow parts and bed or cab accessories around the way you use your truck. Identify generation, engine, drivetrain, cab, bed and any Raptor or Lightning configuration before choosing parts.Suspension Systems or Individual ShocksICON titles distinguish different stages, arm configurations and production ranges. Bilstein front-kit and Fox coilover or rear-shock references cover separate drivetrain and height applications. Define the desired stance and intended use, then match actual suspension and travel requirements with the installer. A component box, rear lift part or shock pair is separate from a complete system with all required arms, brackets and alignment hardware.Engine-Specific Airflow and ServiceInjen and Roush intake references name different engines and production ranges, while aFe Raptor R and GSC Coyote camsh...

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. An adapter chang...

Compare throttle-body spacers, adapter plates, couplers and gaskets for a defined intake installation. Shop aFe Silver Bullet, Airaid PowerAid, Torque Solution, do88, COBB, GReddy and other listed references. Match the actual throttle body, manifold and intake arrangement before choosing the spacer or connection component.Application-Specific SpacersA spacer installs at the specified throttle/manifold interface. 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.
