More Air, Better Throttle Response for the 1987-1989 GMC V3500

The aFe Silver Bullet throttle body spacer 46-34004 increases air velocity and induces a helical charge spin effect that improves air/fuel mixing before the intake manifold runners for the 1987-1989 GMC V3500. The machined aluminum spacer installs between the throttle body and intake manifold using factory hardware, adding measurable low-end torque and throttle response without any permanent modification. The 46-34004 works synergistically with a cold air intake or exhaust upgrade for maximum return.

Key Features

  • Helical bore design creates charge spin effect for improved air/fuel mixing
  • Precision-machined aluminum construction
  • Direct bolt-on installation using factory hardware
  • No modification to factory throttle body or electronics
  • Compatible with cold air intake and exhaust upgrades for compounding gains
  • Finish: silver anodized
  • Backed by aFe Power limited manufacturer warranty

Frequently Asked Questions

Will this require a tune after installation?

A throttle body spacer is a bolt-on part that does not require a tune in most applications. The ECU adapts to the slight change in intake dynamics during normal closed-loop operation.

How much power gain can I expect?

Throttle body spacers are primarily a low-end torque and throttle response upgrade. Most users report noticeable seat-of-the-pants improvement in initial throttle application and idle quality.

Does this affect idle quality?

In most cases, no. A direct-fit throttle body spacer maintains the factory idle air control system. Allow the ECU time to relearn idle parameters after installation. If idle quality issues arise, check for vacuum leaks at all manifold and spacer joints before drawing other conclusions.

Is this reversible?

Yes. The spacer bolts in-line between the throttle body and manifold using factory hardware. Removing it and reinstalling the factory configuration takes less than an hour.

Does this work with my cold air intake?

Yes. The 46-34004 is fully compatible with aftermarket cold air intakes and other intake system modifications. Running a complete intake system with this throttle body spacer delivers compounding airflow improvements.

Will this void my factory warranty?

Under the Magnuson-Moss Warranty Act, a dealer cannot void your factory warranty solely because you installed an aftermarket throttle body spacer. They must demonstrate a direct causal link to any specific failure. Remove the 46-34004 before any dealer service visit if you prefer not to discuss it.

What is the warranty on this product?

aFe Power provides a limited manufacturer warranty covering defects in materials and workmanship. Contact aFe Power or us for current warranty terms and coverage specifics.

Are any gaskets included?

Yes. The Silver Bullet spacer includes the required intake gaskets for installation on both the throttle body and manifold sides.

Installation Overview

  1. Disconnect the negative battery terminal and allow the engine to cool
  2. Remove the intake tube connected to the throttle body inlet
  3. Disconnect the TPS sensor connector and IAC connections from the factory throttle body
  4. Remove the four throttle body mounting bolts and set the factory unit aside
  5. Clean both mating surfaces and install the spacer using new gaskets
  6. Reinstall the factory throttle body onto the spacer using the original hardware
  7. Reconnect all intake plumbing and vacuum lines
  8. Reconnect the battery and start the engine to confirm normal idle
  9. Allow the ECU to complete an idle relearn cycle before performing a WOT test
