fail… you need a “highflow” manifold, uppipe, downpipe, TIP, injectors and then find a k04-20 file… waste of time for 250-270whp… its still a k0-x… this isnt an S4 where you can get away with k03/k04s and be fast
plus the k04-20 makes ALOT of torque, and several people have bent rods/windowed blocks using them
