I mean, I know what sri means, but I'm trying to figure out what's so bad about them. Do they decrease your mpg? Does pulling in more air even if its warm worse than that stock air box? Things like that. Also, there are wires plugged into a little plastic thing inside my air box, and no one seems to know what it is. That's the main part I'm trying to get help with. Number one, what the hell is it!!! And number 2 what can I do with it. Can I move it? Etc..... can u help. Its driving me nuts!
