Turbocharger Inlet Seal Type
- Early Style - used on most pre-2008 Mercedes models. Has one row of round pegs.
- Late Style - used on 2008+ Mercedes models. Has one row of round pegs PLUS square shaped pegs at the front edge.
Important! New replacement Y shaped inlet pipes from Mercedes use the new style seal, so some Early models may use the late style seal if the turbocharger inlet pipe was ever replaced.
