This is a reference application; verify physical dimensions and housing interface to ensure correct fitment for your rebuild or replacement project.

Technical Notes

The TO4E66 turbocharger is a fixed-geometry unit, so this compressor wheel operates with a static vane profile. Buyers should verify the wheel diameter and blade sweep against the existing component to ensure proper airflow characteristics for the OM366A engine. The machined metallic surface finish and radial vane arrangement are visible in the studio images, which help confirm the physical interface with the compressor housing. Since material grade and specific dimensions are not explicitly listed, cross-reference the part number 442293-0003 and OEM reference 442293-3 with your current turbo tag. This verification step ensures the replacement wheel matches the required balance and rotational speed for stable operation during rebuilds.
