these came with a bunch of parts i picked up. I'm pretty sure these are IDA's. They are T1 and welded for a D port intake.
i'm into T4's and IDF's, so these won't work for me.
i don't know what these are worth, so if you want them make me an offer you think is fair and they will be yours.
they are on the island, but i can ship no prob. these are super light.
