    S54 and S50 pistons

    Hello!
    Im sure that this subject is more than covered, but i couldn`t find the answer!
    Are S54 or S50 OEM pistons forged?

    Thanks!

    S54 pistons are cast, lined with graphite.

    The S50 pistons are not forged either, the rods and crank are though.

    Are these at least hypereutectic (16-19% of silicon)
    Or just cast aluminium pistons? (less than 12% silicon)??

    I can't tell you. I'd assume the cheapest.
