Important Fitment Note
This product is a rebuild kit only. It is not a complete turbocharger, CHRA or actuator. K03 and K04 turbochargers have many variations, so the turbo model alone is not enough to confirm fitment.
Please compare your original turbo part number, bearing type and repair kit components before ordering. If you are not sure whether this kit fits your turbocharger, send us your turbo nameplate or OEM number for confirmation.
