JET Performance Power-Flo Throttle Body Spacers are designed using the latest aerospace technology along with JET's 35 plus years of engineering fuel systems for some of the world's top drag, off-road, circle track, and marine racing teams.

The bore of these spacers is engineered to increase the velocity of airflow into the intake manifold. By delivering the air with more velocity, more air reaches the combustion chamber for a denser air charge. This design results in improved throttle response and impressive power gains in the mid range and top end. In addition, the increased airflow results in better overall fuel efficiency. Installation is simple, just bolt-on with no other vehicle modifications required. They are precision machined out of billet aluminum by JET's in-house CNC machine shop. These TBI Spacers are compatible and recommended with other aftermarket upgrades, such as cold air intakes, free-flow exhaust systems, etc.
