Wehrli’s -10AN extended turbo oil drain fitting kit relocates the threaded drain connection away from the turbo center section for easier wrench access, using a black anodized billet aluminum drain flange with an extended #10AN drain tube. The adapter flange uses a reusable O‑ring seal to eliminate torn paper gaskets, extends the -10AN male fitting 4" from the turbo, and is compatible with T3/T4/T6 mid‑frame turbochargers that use 2" on‑center bolt spacing.
