Product Details
This listing is for a single JE Pistons forged piston designed for BMW N54B30 engines. You'll receive one piston, a high-quality wrist pin, locks, and JE Pro Seal premium piston rings, all made in the USA. This piston features an 84.5mm bore and a 9.5:1 compression ratio, with an inverted dome/dish design.
JE Pistons uses 2618 aluminum for these pistons, which offers the high tensile strength needed for demanding performance applications. They are forged and machined in the USA, with a design specific to the N54B30 engine for optimized performance and durability. Features like the proprietary Forged Side Relief (FSR) design help minimize friction and power loss, while a skirt coating, if applicable to this specific application, further reduces friction and wear on the cylinder walls, also helping to quiet down operation. An accumulator groove, also dependent on the specific application, can help manage combustion gas pressure for improved ring seal and consistent power delivery.
This piston is intended for performance builds where durability and power are key. Please note that this part is not CARB approved and cannot be shipped to California.
