"Took about an hour to install. Had a couple hoses that didn't show on the directions that restricted how far I could move the throttle body. I installed this with a K&N panel filter. I was getting 16.5 MPG before the install and now I am getting 17.4 MPG driving in town and on the highway. The truck seems to have more throttle response and I have not heard any whistle. I was hoping for 18-19 MPG on the highway but it is what it is. Overall not a bad product." —Jamey M from Sedalia, MO bought an Airaid PowerAid Throttle Body Spacer for a 2006 Chevy Avalanche, 1500, 5.3L V8.
