    Can we do the TB coolant bypass on our cars? I noticed my tb doesn't get as hot as my 2006 Mazda 3, so I wonder if the tb is heated. Even after lots of driving, it's luke warm at best, but then again it's cold outside.

    I've searched for threads on this and found some info, but I have another question for those who have it or know. Does a CAI Bypass valve restrict any gain that would have been had by the CAI? Does it suffer a performance decrease because of it? Just for example, really: 2.75" 70mm Cold Air...
