Throttle Body Spacer - I bought one on eBay and put it on. The air made a nifty noise when you hit the gas. It made a 20% difference in mileage. MPG went from 16.8 to 13.6. I took it back off and sold it after two days. MPG went back up to 16-17. If you really want to try one, look on eBay. There's lots of them for sale there pretty cheap.
