Reviews of OEM BMW pistons

This piston came out of my N52b30 with around 220000 km. It was kept pristine, ran it on thrice the volume of oil additives as per the forums recommend, along with 30/70 racing coolant additive to HOAT+ approved coolant. The car was being driven moderately hard, and not on smooth roads.

But in europe its best to get early b25 (85-87) pistons for higher compression(9.75.1), late model pistons (8.8.1) work fine aswell but just a little bit lower compression so a little bit lower performance.
