Review on Enhance Performance with Airaid 200-540 PowerAid Throttle Body Spacer by Jeff Jordan

Installed on a 95 Silverado Z71 350 TBI pickup. My truck has standard semi-aggressive tread tires, works really well and I've gone from 14mpg to 15.2-15.8 depending on what I'm doing. a day because I drive a lot and I got a solid 1-2 mpg. The truck has better throttle response, it idles a little harder but not bad at all, well worth the money spent on it if you have a tbi car get this item!
