POWR-FLO TBI SPACERS
The JET Powr-Flo Throttle Body Spacers use aerospace engineering combined with years of experience in tuning every type of vehicle from NHRA drag race cars, off-road race trucks, Winston Cup Race Cars and performance street applications.
The exceptional design of the bore of the Powr-Flo Spacer causes the incoming air flow to actually smooth out and speed up. This creates a type of compacted air-charge that enters through the throttle body and builds pressure in the combustion chamber.

This will result in an extensive gain in the mid-range power band and an overall increase in fuel efficiency.
