Jeep YJ Throttle Body Spacers for Wrangler (1987-1995)

Throttle response sharpens when Jeep YJ Throttle Body Spacers for Wrangler (1987-1995) create turbulent airflow that improves fuel atomization entering the intake manifold. These simple bolt-on components add plenum volume and create swirling air patterns that help extract a bit more power from the venerable 4.0L and 2.5L engines.
