Overview
The Jet Performance Products Powr-Flo TBI spacer, part 62116, is an anodized billet aluminum throttle body spacer for Jeep vehicles from 1987 to 2001. Listed models include the Cherokee XJ, Wrangler YJ, Comanche, Wagoneer SJ and the Wrangler TJ SE.
The serrated bore raises air velocity into the intake manifold, which delivers a denser air charge and improves throttle response in the mid range and top end. The spacer is designed for bolt-on installation.
Key features
- Billet aluminum construction with anodized finish
- Serrated bore designed to raise air velocity into the manifold
- Improved throttle response and added power, per Jet
- Bolt-on installation
- Works with air intakes, computer mods and high-flow exhausts
Intake and fueling balance
A TBI spacer raises the throttle body above the intake, which changes how air and fuel mix as they enter the manifold. On carbureted or throttle-body fuel systems, that shift can alter idle and part-throttle behavior, so the way the engine is tuned matters. Look at the air filter, intake hoses and PCV connections as well, since any leak after the spacer will affect how smoothly the engine runs.
When choosing parts to pair with this spacer, focus on items that move the same airflow, such as an intake that matches the throttle body opening and an exhaust that does not restrict the engine. Keep the gasket and hardware in good condition, and check the bolts for tightness after the first few drives. A spacer that is seated flat with a fresh gasket is the simplest way to get predictable results from any upgrade.
