this one guy got some aftermarket p72 pistons, made by top line?? or something but he couldn't tell me if it OEM or AFTERmarket or is it all the same. ..
and is all pistons including oem/aftermarket pistons FORGED???? to withstand heat... to a certain degree??
or is it just for aftermarket app
becuz i'm debating on picking them up . but would it be a good choice for using it for boost???
