Hi what's the difference between the k04-015 and the k04-020 besides £100 on e-bay can the 015 be made into a 020?
What's the difference?
- Thread starter A4 nut
- Start date
Just been back on e-bay and found a k04-022 im now looking at all 3 what would be the best buy for a 163 bhp A4 if i want an output of arround 250 bhp
Brinkster (LINK) and VWVortex (LINK) both have good info on this (not that I'd know enough to say any different to what they're preaching 
).... and you left the "K04-025" off that list Or is that for the V6's B5-RS4) only?
