If you are using the regular file, you probably won't even need new injectors but you do need the 5 bar FPR. Also, make sure you check your oil return line carefully as this is critical on the K04 if full flow isn't there. I would recommend getting a new one if there is any doubt on thecondition. 034 sells one that is a lot cheaper than stock. These are just a couple of things I wish people had told me before my install. Good luck on your install.
