The finished product:  Homebrew CAI.  During a run to the local Walgreens to get these pictures developed, I performed a preliminary test of the CAI.  The tone is for the most part normal under normal driving conditions (i.e. mild throttle).  A deeper tone is achieved under moderate throttle.  I haven't had a chance to go FOT with it yet, so I don't know whether there is significant power gain.  Low end torque feels a slight bit higher, but it could be my imagination.  I'm going to monitor the condition of the CAI for a few months to make sure everything holds up.  Hopefully, the caulking can withstand the vibration.  If not, I may need hints on cleaning the throttle body...  I will continue my observations as they become available.  Final cost:  ~$80-90.
