Installation Notes and Tips

Inspect the mating surfaces before installation and replace the seal if the original O-ring shows flattening, cuts, or heat damage. Clean the turbo inlet and adjoining components so the new seal seats evenly, and verify the correct OE reference before installation on your Mercedes-Benz Sprinter, C250, E250, or SLK application.
