I have a question about the hacked air box. I was looking at a stock intake system on another car, and I was rather perplexed.There's a sensor before the filter and one afterwards. How would He go about chopping his air box....I couldn't figure it out at all. If he hacks before the filter, more air will be going in that the sensor will read, so he won't get the right air\fuel mixture, right? and you can't hack after the filter....so got any suggestions?
