BMW S50B30 Piston Set - ItalianRP IRPP026DA
The ItalianRP pistons are designed for the BMW M3's S50B30 3.0L 24-valve engine, commonly found in models from 1992 to 1995, but only from 1994 to 1995 in the United States. These pistons are available in three variants—Silver, Gold, and Platinum—each catering to different performance needs. The Silver line is crafted from 4032 aluminum, ideal for street applications; the Gold line utilizes forged 2618 aluminum for enhanced strength; and the Platinum line, also forged from 2618 aluminum, features a double bridge design for superior durability and performance. All variants maintain the compression ratio of 12.60:1 and are compatible with the standard 86.00 mm bore size, but also come in three other bore sizes.
