Silver Bullet spacer for exact engine and intake requirements

The aFe 46-37002 Silver Bullet spacer is for the exact 3.5L V6 applications listed in the linked installation manual. Broad retailer and older emissions tables do not establish compatibility with every later Honda/Acura or hybrid.

Key Features

  • 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
  • 6061-T6 billet aluminum with serrated/helix entry.
  • The current page supports the factory intake or listed aFe TR-1007B/P and TR-1021B-R/P-D configurations. The manual warns aftermarket tube adjustment or trimming may be necessary; verify the exact installed intake.
  • Manufacturer response and power claims do not guarantee gains.

46-37002: The August 2021 exact manual is narrower than retailer fitment and older EO D-550-17. Legacy MDX/RLX/TLX, 2016 Pilot and 2017–2019 Ridgeline rows are withheld as source conflicts; this is not proof those vehicles are physically incompatible. Sport Hybrid compatibility is not established by the manual, and the unsupported RLX plug-in-hybrid search classification is removed. The documented 2010–2011 Accord Crosstour application and matching existing native collection are restored. Named Accord/Crosstour/TSX trims remain conditional on the 3.5L engine.

Throttle-body fastening The exact manual specifies 15 ft-lb for the four supplied M8 screws.
Emissions scope The page cites D-550-17 / D-550-47 but prints 2.4L test groups on this 3.5L page. That apparent cross-listed disclaimer is not a verified exclusion list for this part. The newer EO could not be read; exact test-group exemption remains open. Older EO model coverage does not resolve the narrower mechanical manual.

Frequently Asked Questions

What is the 46-37002?

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 gasket sits between the spacer and throttle body. AIR IN points toward the throttle body.

What is the correct torque?

The exact manual specifies 15 ft-lb for the four supplied M8 screws.

Are all original search rows certified?

The August 2021 exact manual is narrower than retailer fitment and older EO D-550-17. Legacy MDX/RLX/TLX, 2016 Pilot and 2017–2019 Ridgeline rows are withheld as source conflicts; this is not proof those vehicles are physically incompatible. Sport Hybrid compatibility is not established by the manual, and the unsupported RLX plug-in-hybrid search classification is removed. The documented 2010–2011 Accord Crosstour application and matching existing native collection are restored. Named Accord/Crosstour/TSX trims remain conditional on the 3.5L engine.

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 cites D-550-17 / D-550-47 but prints 2.4L test groups on this 3.5L page. That apparent cross-listed disclaimer is not a verified exclusion list for this part. The newer EO could not be read; exact test-group exemption remains open. Older EO model coverage does not resolve the narrower mechanical manual.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-37002, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Match the exact engine and manual. Remove the engine cover, disconnect the crankcase hose, loosen the intake clamps and remove the intake tube.
  3. Remove the two throttle-body screws and two nuts. Remove the manifold studs using the instructed double-nut method; retain original hardware.
  4. Install the spacer with AIR IN toward the body and the supplied gasket between spacer and body.
  5. Use the four supplied M8 x 80mm screws, lock washers and flat washers. Tighten to 15 ft-lb.
  6. Restore the intake tube, crankcase hose and clamps, checking any required aftermarket-intake adjustment before proceeding. Do not copy the four-cylinder kit's specific cutting dimension.
  7. Recheck bolts and clamps after 100 miles and verify exact EO/underhood test-group requirements before use.

46-37002: installation details and any unresolved source scope must be matched to the actual vehicle before use.
