Choosing and fitting a spacer
A throttle body spacer moves the throttle body farther from the intake opening, which changes how air reaches the throttle plate. On a truck that already runs a stock air intake and a tuned computer, the result is usually subtle, so expectations should match a modest change in how the engine feels under load rather than a dramatic gain. The spacer works best as one part of a set of airflow changes, not as a stand-alone fix.
Before buying, consider what else is on the truck. Intake tubes, air filters and exhaust work all affect airflow, and a spacer does not replace any of them. If the throttle body gasket or intake gasket is worn, replace it when the spacer goes in, since a new seal prevents vacuum leaks at the joints.
- Inspect the throttle body and intake flanges for cracks before reinstalling.
- Re-check the mounting bolts after the first few drives.
- Clean the throttle plate before installing if the throttle body is accessible.
