i found out about these heater tap prices when i found a (perfectly working) alfa romeo item in my car. i thought, WTF and went on the hunt for a NOS toyota item and found out why a previous owner had done the swap. needless to say, i still have the alfa part in there. if the core does break in my car i'll just rip it out and claim 'race car lightness' as a reason for not having it. :D
