WHY WE SHIP XONA ROTOR
We carry Xona Rotor for builds where the power target has outgrown what OEM or direct-replacement turbos can support. Their specs are published in engineering terms — inducer diameter, rated lb/min airflow, turbine outlet size, housing A/R — and the model names encode those specs directly, so there is no guessing what you are ordering. These are not bolt-on upgrades: all BMW applications require custom intake manifold and downpipe adaptation, and housing configuration is chosen per build. We specify that configuration when you contact us.
