The aFe 46-37004 black Silver Bullet spacer is for the listed Honda/Acura 3.5L V6 applications. It includes a gasket and hardware for the original throttle body, not a replacement throttle body or full intake.
| Years / source scope | Model | Exact requirements |
|---|---|---|
| 2014β2020 | Acura MDX / RLX | 3.5L V6; exact engine/version required |
| 2015β2020 | Acura TLX | 3.5L V6 only; not four-cylinder |

46-37004: The linked exact manual documents all seven model families above. The current page extends Ridgeline through 2026, whereas its manual ends at 2024; that difference is qualified rather than copied to the other Honda models. New broad year coverage uses model-level entries and does not certify every named trim, hybrid or engine revision. Existing Acura rows remain conditional on the exact 3.5L engine; no Sport Hybrid compatibility is inferred.

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?Place the supplied gasket between spacer and throttle body, with AIR IN toward the throttle body.
What is the correct torque?The exact manual specifies 15 ft-lb for the supplied M8 x 80mm screws.
Are all original search rows certified?The linked exact manual documents all seven model families above. The current page extends Ridgeline through 2026, whereas its manual ends at 2024; that difference is qualified rather than copied to the other Honda models. New broad year coverage uses model-level entries and does not certify every named trim, hybrid or engine revision. Existing Acura rows remain conditional on the exact 3.5L engine; no Sport Hybrid compatibility is inferred.
Can another spacerβs 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-550-47 and excludes FHNXV03.5VK2, GHNXV03.5PK3, EHNXV03.52G2, JHNXV03.5BK3, KHNXV03.5FL3 and HHNXV03.5LK3. Match the actual underhood test group. The full official order could not be independently read, so remaining model-year/test-group exemption is not fully certified.
