The Powr-Flo spacers ' bore is designed to increase the velocity of the air flow into the intake manifold. By delivering the air with more velocity it allows more air into the combustion chamber for a denser air charge. The design results in improved throttle response and impressive power gains in the mid range and top end.

I installed it on my 98 Cherokee, and it felt lighter. I haven't driven the vehicle enough to see if there is any difference in gas mileage. Installation was so easy, fits perfect and looks great.
