Good To Know

Q: Do I need to weld this fitting to the oil pan? A: No, this is a weld-free adapter that uses a backing nut and seals to compress against the side of the oil pan hole.

Q: Why is 10AN size recommended for turbo drains? A: Turbo oil drains rely on gravity, so a larger line like 10AN prevents oil from backing up and leaking past the turbo seals.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
