stock pistons ?

[israelcj7]

today i tore apart a4.0 liter engine and i took a close look on the pistons, they have this part number :bd j3241156.the pistons are std(3.875).
my question is who makes them?
are they OE pistons?

and i have another piston,brand new 0.30 over that have a part nomber: pc2322 ,
do you have any spec's on that one?
are they any good for a stroker ?

thanks

The j3241156 are just stock pistons.

Can't find any info on the pc2322
