OK guys. I spoke w/ a tech(Mike?) at AEM before they released their shorty for the Pro2.0. He said that they thoroughly tested the benefits of a short vs. a CAI, and after they had finished their research they decided that the most beneficial gains were garnered from a short ram. He did note that each had different benefits depending on where you were in the RPM curve, but their testing proved "their" short ram produces more power than the competitors CAI's as well as their own that they developed for testing. I don't know how many have seen the AEM shorty for the Pro2.0, but the 2 pc construction heads south, then attaches to the bracket extending from the coolent overflow. From this fairly open area, the filter then extends downward, drawing "cooler" air than most conventional short rams. Just my 2cents, but there it is. I'll have to admit, I'm a dedicated fan of nearly everything engineered by AEM. Who knows though, after time they will probably develop a CAI as well just to prove me wrong.
