BD's adapter flange lets you run a different turbo flange without replacing the exhaust manifold, and makes it quicker to switch back and forth between T4 and T3 turbos.
It is machined flat to 0.480 in so it seals in exhaust drive pressure.
Who it's for
Owners changing turbos between T3 and T4 flanges.
