Genuine Borg Warner RS4 K04 Turbocharger Set
Upgrade the stock K03 turbos on your Audi 2.7T with genuine Borg Warner RS4 K04 turbochargers. This is for a pair(Right & Left).
These will produce an overboost condition if not properly tuned.
We have have sold, built and tuned on hundreds of stage 3 cars and have seen in excess of 400whp on 93 octane with these turbos. We have countless customers with over 100k miles on genuine Borg Warner K04's with no noticeable shaft play. Everyone will not see the same results since there are multiple factors like hardware, tuning, etc that play into turbo lifespan.
This is NOT a full bolt on kit.
