Pretty sure AUM injectors are different to agu as they are more like s3 fitment therefore 550s as listed above are the ones you need. Red and green tops won't cut it and won't directly fit. Either go for some stock s3 injectors at 380cc for around 300bhp then get some 550s for upto 340bhp above that you'll need 630cc ones .
Or get 380cc then fit a 4 bar fpr and s3 fuel pump to get more bhp.
