The 3.5L Twin Turbo is referring to the engine in some of the Genesis models. So unfortunately, no the Stinger doesn't have a hidden 3.5L TT (would be awesome though ).
I did see that one come up, I didn't like how jagged the edges were. I ended going with this one:Like this?
Just out of morbid curiosity i checked the cost on an OEM. Right at $400 at my dealer, and willing to hook me up with a 50 buck discount if i want one. Good or bad my dealer knows who i am so they step up for meIt probably wouldn't be that bad but I don't see it for sale anywhere. All the parts I am finding are for 18-21 only.
