The PowerAid throttle body spacers from AirAid premium filter company are designed to greatly improve the low-end torque and horsepower characteristics of your engine. PowerAid accomplishes this by spacing the throttle body one inch and adding a dyno-proven Helix style bore(s). As the intake air passes through the spacer, the Helix bore creates a vortex action that improves atomization creating a more complete combustion and an efficiently burning engine. The results are improved drive-ability and increased fuel efficiency.
This throttle body spacer from AirAid will greatly improve your Aspen's all around performance.
