[Rau]

so my K03 is dying on me ( ususal symptoms, smoking at the light ) and I wanna upgrade to a K04. Do i need to chip it or run some kind of software, or is it just bolt on?

K04
The ko4 that you want is the ko4-15. Basic bolt in upgrade. No special required parts unless going for the pc-16, J31, or Hammer files from GIAC. Do not pay more than $800 for a K04 alone. They can be found on any of the various Audi forums for less. GIAC makes a very good program for it. $1300 and an install later you can be rolling with 200whp. When looking you will need the K04-15. do not bother on doing a ko4 for your 2001 A4 if you are not going with the Hammer file. the 2001 model year has the ko3s(sport) so there for the GIAC-X chip with the ko3s will only be slightly less powered than the ko4 on basic GIAC programming. for knowing what you need for these setups contact GIAC directly. as it will be easier than me typing it all out. KineticMotorsport has them for a good price usually

PC-16 - 1997-1999.5 model years~usually runs in the 20-25psi range
j31 - 2000~usually runs in the 25-28psi range
Hammer - 2001 and 2001.5~i think usually runs in the 20psi range

You will also need injectors, fpr, and a front mounted intercooler. And a custom exhaust w/either a test pipe or high flow cat would make it complete.
