After installing the Airaid CAI, I wanted to add a throttle body spacer. I was very pleased with Airaid so going with them was a no-brainer. After the CAI I gained roughly 1 mpg, that is highway driving with average speeds of 70 mph speed limit. I rechecked the mpg after the TBS and I gained an additional MPG. That might not sound like much, but I have went from 16 mpg to 18 mpg. I have gained 32 miles per tank of gas. That is almost an entire round trip to and from work. That saves me 300 hundred dollars per year driving 15,000/year and $3/gal of gas. Not too bad. Plus the whistle is audible and sounds really cool. The instructions are lacking, but the ones on the internet are in color and a lot easier to see. FYI cut the waffle thing out, that is in the intake pipe on the engine side of the throttle body.
