The only way I know to get one in the US, other than second hand or Elevate, is through a BorgWarner distributor. Part number is 5316-998-0010. And yes, you’ll need at least the genuine K16 oil drain line. K04 drain line will not fit, and cannot be adapted easily (different shape, see here). The stock coolant lines will bolt right up to the K16. All banjo bolts are the same.
Here’s the part list:

Then, depending which tune you go with. You’ll have to upgrade fuel injectors (at least 550cc. Some tuners like Penta Performance recommend 750cc), go with step colder spark plugs (NGK LFR7AIX), upgrade the MAF (AFAIK, Hilton it’s the only one that recommends it, and he’s got a valid point with that). And at this point it’s more than obvious to mention it, but you’ll need upgraded intercooler, intake pipe, downpipe, and just to be safe, a shimmed block.
