Powr-Flo TBI Spacer

The JET Performance Powr-Flo TBI Spacer (SKU JET62165) is a throttle body spacer engineered to enhance intake manifold efficiency on GM High Feature V6 engines. This 1-inch thick aluminum spacer positions the throttle body at an optimized distance from the intake manifold, improving airflow dynamics and fuel distribution characteristics across the engine's rpm band.

Constructed from blue anodized aluminum, the Powr-Flo spacer resists corrosion while maintaining thermal stability under engine bay conditions. The 1-inch spacing geometry is specifically calibrated for GM High Feature V6 applications to maximize the velocity and distribution of the incoming charge without restricting flow. The spacer includes gaskets and all necessary hardware for direct bolt-on installation, eliminating the need for aftermarket fasteners or modification to existing mounting points.

Buyers targeting improved throttle response and more consistent fuel atomization on naturally aspirated GM V6 engines choose this spacer as a bolt-on solution that requires no tuning adjustments or engine modifications. The design works within factory sensor and fuel injection parameters, making it compatible with stock engine management systems. Installation typically takes 30 minutes and reverses without residual damage, allowing straightforward comparison of intake manifold performance before and after installation.

JET Performance positions this spacer in the bolt-on efficiency category—a category favored by GM V6 owners who want measurable intake flow improvement without forced induction or major engine work. The blue anodize finish serves both aesthetic and protective functions, visibly signaling the upgrade while extending service life in moisture-prone environments.
