JE Pistons BMW S14B2 13:0 KIT Set of 4 Pistons

JE Pistons is known for making well-built forged racing pistons, using over 75 years of experience to create parts for many different engines. This specific piston kit is built for the BMW S14B23 engine, designed to give you the durability and performance needed for high-demand applications. Each piston is forged and machined right here in the USA from 2618 aluminum, a material chosen for its strong tensile strength, which is essential when you're pushing an engine hard.

This kit includes a set of four pistons, each featuring JE's proprietary Forged Side Relief (FSR) design. This design helps minimize friction and power loss by using a reduced skirt width and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove, which helps reduce pressure from combustion gases, leading to better ring seal and more consistent power. Some applications also include a skirt coating to further reduce friction and wear on the piston skirts and cylinder walls, which can also help quiet down engine noise. These pistons are designed specifically for the S14B23 engine to optimize performance and durability.

When you get this kit, you're not just getting pistons. It comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have the essential components ready for installation. Remember, this kit is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly details.
