Silver Bullet spacer for exact engine and intake requirements

The aFe 46-34018 fits the specified five-cylinder GM compact-truck installations. It does not approve four-cylinder or V8 engines that share Colorado, Canyon or H3 model names.

Key Features

  • 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
  • Current page headline and exact manual agree on the Colorado/Canyon engine-year split.
  • Factory air-cleaner resonator, crankcase ventilation and atmospheric vent connections are reinstalled; no replacement filter or coupling appears in the exact parts list.

Fitment

Years / source scope Model Exact requirements
2004–2006; 2007–2012 Chevrolet Colorado / GMC Canyon L5 3.5L; L5 3.7L respectively
2006; 2007–2008 Hummer H3 L5 3.5L; L5 3.7L respectively; not the V8 Alpha
2006; 2007–2008 Isuzu i-350; i-370 L5 3.5L; L5 3.7L respectively

46-34018: The exact manual separates the 3.5L and 3.7L years and names the H3 and Isuzu applications individually. Existing model/grade search rows remain conditional on the five-cylinder engine; a shared model name is not approval of its four-cylinder or V8 alternatives. The page title calls the spacer silver while its overview says black anodized; actual finish/revision has not been physically verified.

Frequently Asked Questions

What is the 46-34018?

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; engraved face toward the throttle body.

What is the correct torque?

Throttle-body bolts: 89 in-lb. The two air-cleaner resonator mounting bolts have a separate 53 in-lb specification.

Are all original search rows certified?

The exact manual separates the 3.5L and 3.7L years and names the H3 and Isuzu applications individually. Existing model/grade search rows remain conditional on the five-cylinder engine; a shared model name is not approval of its four-cylinder or V8 alternatives. The page title calls the spacer silver while its overview says black anodized; actual finish/revision has not been physically verified.

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 exact page says this part is not CARB exempt and is unavailable for California purchase or use on California-registered vehicles. Do not inherit an EO from another GM spacer.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-34018, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Disconnect the atmospheric vent hose, loosen the resonator outlet clamp and remove its two mounting bolts. Lift the assembly while disconnecting the crankcase ventilation hose and throttle-body outlet duct.
  3. Remove the four throttle-body nuts/studs; the manual suggests a 4 mm six-point socket. Face the spacer engraving toward the throttle body and place the supplied gasket between them.
  4. Use the supplied longer bolts and flat washers to secure the throttle body to 89 in-lb.
  5. Reinstall the outlet duct and crankcase ventilation hose, align the resonator mounting hardware and tighten the outlet clamp. Tighten the two resonator mounting bolts to 53 in-lb, then reconnect the atmospheric vent hose.
  6. Inspect every hose, clamp and mounting connection before operation.

46-34018: installation details and any unresolved source scope must be matched to the actual vehicle before use.
