The end result is more part-throttle torque and improved mid-range power. The AIRAID Throttle Body Spacer is designed to enhance mid-range torque using a patented Helix Bore which spins intake air going through the throttle body spacer.
Buy something else - This spacer is 3/4 thick, not 1". The included plenum bracket spacer is also a corresponding 3/4". My spacer needed to be redrilled several times for the holes to be in alignment. The bracket for the plenum also had to be ground down in order for the spacer to fit properly. The the bolt for the spacer was also too short along with the four bolts for the throttle body. So include a trip to the hardware store to get the right bolts. Should also mention the bolts provided for the throttle body we're not flanged like the factory bolts. Buy a different kit -
