BMW M3 Piston Sets - Supertech - 4032 Forged - `96-`00. These are Supertech forged 4032 alloy pistons made for the E36 M3 S52/B32 3.2L engines, supplied as a set of six pistons (rings not included).

Designed for enthusiasts who want a durable, direct-fit replacement for the 1996–2000 E36 M3, these 87.0mm pistons use 4032 forged aluminum for improved fatigue resistance compared with typical cast pistons. They are manufactured to OEM-style dimensions to fit stock connecting rods and blocks without major machining, making them suitable for rebuilt engines, performance refreshes, or mild power increases when combined with appropriate supporting components. Exact fitment is for S52/B32 3.2L applications; rings and additional hardware must be purchased separately.
