Silver Bullet spacer for exact engine and intake requirements

The aFe 46-34005 is for the specified later 5.0L/5.7L GM C/K throttle-body arrangement. It uses an O-ring-up installation, a rear mounting stud and a cable-bracket extension; it is not the earlier two-gasket TBI kit.

Key Features

  • 6061-T6 billet-aluminum serrated/helix entry design; claimed turbulence and reduced whistle do not guarantee an improvement on every setup.
  • Two front mounting bolts plus the rear stud/nut secure the body; the third supplied bolt serves the cable-bracket extension arrangement.
  • The page’s generic gasket prose and Filter Included / Coupler Included fields do not override the exact manual’s O-ring and hardware list.

Fitment

Years / source scope Model Exact requirements
1996–2000 manual / current family GM C/K 1500 / 2500 / 3500 V8 5.0L / 5.7L, exact original throttle-body assembly
1996–1999 exact manual GM Suburban V8 5.7L
1996–2000 exact manual Chevrolet Tahoe V8 5.7L; actual body generation and assembly must match

46-34005: The family ranges do not certify every engine or grade, nor interchange a later Silverado/Sierra electronic-throttle assembly with the older C/K arrangement. Missing C/K 1500 search coverage is restored conservatively within the documented 1996–1998 model range; later Classic/model-name and remaining SUV mapping require exact taxonomy/assembly confirmation. Existing 2500/3500 grade rows remain engine-conditional.

Frequently Asked Questions

What is the 46-34005?

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 O-ring; the manual orients the O-ring side upward. A flat gasket is not listed in this exact kit.

What is the correct torque?

Throttle-body fasteners: 10 Nm (89 in-lb), with no overtightening. Do not transfer the earlier TBI kit’s 12 ft-lb limit.

Are all original search rows certified?

The family ranges do not certify every engine or grade, nor interchange a later Silverado/Sierra electronic-throttle assembly with the older C/K arrangement. Missing C/K 1500 search coverage is restored conservatively within the documented 1996–1998 model range; later Classic/model-name and remaining SUV mapping require exact taxonomy/assembly confirmation. Existing 2500/3500 grade rows remain engine-conditional.

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 references D-550-11 and D-550-17, with an application-specific exemption disclaimer. Confirm the actual engine/year/assembly against the executive-order table; the family headline is not universal certification.

Installation Instructions

  1. Read the exact manufacturer instructions for 46-34005, verify the actual engine, intake, hardware and applicable emissions scope before removal.
  2. Remove the air-inlet pipe and release the throttle-cable bracket at the body and manifold. Remove the three body bolts, separating the rear bolt from the air-cleaner extension when required; retain the extension.
  3. Install the spacer with its O-ring side upward. Fit the supplied rear stud, then secure the throttle body with the two front bolts and the rear nut/washer. Tighten to 10 Nm (89 in-lb) without overtightening.
  4. Refit the saved air-duct extension on the rear stud. The manual’s cross-reference calls it a part saved from step 4 although removal is described in step 3; retain the actual original extension.
  5. Route the throttle and cruise-control cables over the air-conditioning line as instructed. Reattach the bracket with the original body bolt and the supplied 30 mm extension/bolt/washer at the manifold.
  6. Reattach the air duct with its original wing nut and verify free cable/throttle operation and secure connections.

46-34005: installation details and any unresolved source scope must be matched to the actual vehicle before use.
