I know this thread has been dragging along. I understand everybodies theories or facts, BUT i read somewhere else that you have to put some type of heat sensor inside the intake? Does this attain to the 04+?? I havent even looked at my intake yet since my car is....3 days old now. I would like to go with the DIY cold air system instead of the SLAP A BF filter on. What would the process be? Can i just drill a hole in whatever type of pipe i decide to use? What is the diameter of the TB so i know what size pipe to use? Thanks for all your help!
