Frequently Asked Questions
Are these Plug & Play turbos?
Partially. The oil and water lines fit as they do on the original RS4 K04. Modification of the downpipes is required due to the use of RS6 turbine housings.
What additional parts are necessary?
RS4 B5-specific turbo inlet pipes are required. Downpipes must be modified with a RS6 flange.
Are additional upgrades recommended?
Yes. It is highly recommended to a RS4/S4 B5 upgrade oil pump to be mounted at this power class.
