Looking for a simple -12 AN full flow oil drain flange? Here you go. O ring sealed and the correct size for all of our S400 and Garrett mid frame turbochargers! Comes with flange, oring seal and 2 8mm bolts. If your turbocharger requires 5/16 or 3/8" standard hardware just drop a note when ordering and I will swap them for you! Questions? Shoot me a message or phone call and I will be happy to help.
