Review on 🚀 Maximize Performance with Airaid 510-608 PowerAid Throttle Body Spacer by Rosalio Zavala

I purchased this gasket and cold air intake last Friday (4/24/15) and installed it on my 2009 Scion tC and then filled my tank. My old MPG was 23-25 and now after these mods I'm right at 30mpg. I'm expecting it to get a little better with more power (about 15%) and a complete change in sound just because of the hot rodding I did over the weekend. No more bumblebee noise when I step on the accelerator, just a LOW growl.
