Thought I might throw this out there to someone doing the 6MT conversion, having no need for trans cooling.
This is a Setrab slimline unit that was actually off a B5 V6 setup so the lines might not be correct.
If I didn't already have the custom M3 oil cooler setup on mine, I'd surely use this, as Setrab is about the best hardware out there. (FYI, the stock RS6 oil cooler is bade by Setrab)
