I installed my aFe intake today. That thing really growls! I will likely get the cover to tone it down just a bit. I don't have a feel yet for any improvement in performance (I'm not really expecting any), but I've only driven it a couple of miles so far. The vac hose is definitely too short, and I will be making a stop at the local auto parts store today to solve the issue the same way you did.. The crank case hose is too long. For now, I just have it looping around under the engine cover, but I will trim it when I install the vac hose.
