JE Pistons BMW S14B32 13:1 KIT Set of 4 Pistons

JE Pistons is known for making well-built forged pistons that have proven themselves in racing for over 75 years. They've taken that experience and applied it to this specific piston set for the BMW S14B32 engine. If you're rebuilding the top end of your S14B32 and looking for pistons that can handle serious performance, this set is worth a close look.

These pistons are forged in the USA from 2618 aluminum, which gives them the strong tensile strength needed for high-demand applications. JE uses a proprietary Forged Side Relief (FSR) design that helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, saving weight too. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure, which improves ring seal and keeps power consistent. 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 the engine operation.

This kit is designed specifically for the BMW S14B32 engine to give you optimized performance and durability. It includes everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Just remember, these are not CARB approved and cannot be shipped to California.
