aFe Silver Bullet Throttle Body Spacer – 1987–1995 GM C / K 1500 / 2500 / 3500 4.3L V6V8 5.0 / 5.7L modify the inlet path immediately ahead of the throttle body using a vehicle-specific bolt-on spacer. This listing is built around aFe POWER part number 46-34004 for the 1987–1995 GM C / K 1500 / 2500 / 3500 4.3L V6V8 5.0 / 5.7L.

aFe Silver Bullet spacers are supporting induction components. Their design is intended to influence airflow at the throttle-body entry while preserving a reversible installation with application-specific hardware.

What This Means on the Car

We would not treat a spacer as a replacement for an intake, tune or major airflow modification. Its appeal is the simple installation and its ability to become one small part of a broader induction package.

Legacy Racing Enthusiast Perspective

This is best for the owner who understands it as a supporting bolt-on rather than expecting the type of change associated with a complete intake or calibration. On the 1987–1995 GM C / K 1500 / 2500 / 3500 4.3L V6V8 5.0 / 5.7L, we would make the purchase decision around the limitation this component addresses and how it fits with the car's current and planned modifications.
