I put a 12v Cummins in my 2002 F350, and this manifold is what I needed to move the turbo back from the heater box. Worked great. Turbo spools nicely, I've got no complaints. I'll review again after a few thousand miles

part # on my manifold is 3943874 do you have a replacement?

I do not show any manifolds to cross reference with your part number.

My exhaust manifold has 2 numbers on it, 3943874 and 3943871. It's a 2 piece manifold on a 2002 motorhome.?

You would go with manifold listed under BD-HD-1045987 then.

does this manifold fit 5.9 24valve engine??

The one that list for a common rail would fit a 24v engine. I have seen some motorhomes run a very strange looking manifold. Best to get the part/cast number off yours and call in.-Sands
