Chevy/GMC TBI Injector Spacer

Enhance the performance of your 1988–1995 Chevy TBI small-block engine with our 1/4" TBI injector pod spacer.

Developed through 5 years of research, development, prototyping, and testing, this spacer was engineered to provide a durable, effective upgrade at an affordable price. Each spacer is manufactured from heavy-duty industrial-grade plastic selected for demanding automotive use.

By raising the injector pod 1/4", the spacer provides additional airflow area through the throttle body. Testing demonstrated a 0.39% increase in mass airflow at idle intake pressures and approximately a 200 RPM increase in achievable engine speed at wide-open throttle under our test conditions.

Rather than simply reproducing an existing spacer, we refined the design with a focus on fit, durability, airflow, manufacturability, and cost. The result is a straightforward performance upgrade designed to deliver performance at an excellent value.
