during disassembly one of the egr mating surfaces cracked and broke toyota wanted like $240 or something for a new one, i wouldn't have to pay that since they let me use a employee discount
but it would still be a little pricey so i just picked up a used one from the supramania forum for $15 shipped to my door
i know some are probably thinking just go without one but nahh no thanks unless i was running a jdm ecu and had a block off plate for it and i would like to pass emissions lol
