The difference is 5 and the K04-20 is better by 33%

The K04-20/22/23 are turbos used on the TT225. They will not fit on a B6 without some serious custom fab work.

The K04-15 is a bolt-on (meaning it fits exactly like the stock turbo) upgrade turbo for the A4. The K04-15 can be ordered as a factory option in Europe.

Thanks for the help, because right now i am looking at an A4 and it comes with that K04-15 turbo in it and wanted to know difference from the 20 because its what ive been hearing about a lot. Just another question, but what would be the next turbo upgrade to go after this? When i say this i would like to know how much HP/TQ this one puts out and how much the next one would..

Thanks

Don't forget K04-15 software is readily available, but k04-20/22/23 is much harder to come by.

Someone correct me if I'm wrong.

Try searching for "k04 dyno" on this forum. There will be plenty results.

After the K04 you need something like the APR Stage 3 or the ATP K04 Eliminators (not that many people run these yet though)
