JE Pistons BMW N54B30 84mm Bore 9.5:1 KIT (Set of 6 Pistons)

If you're looking to rebuild or significantly upgrade the engine in your BMW N54B30, this JE Pistons kit is a solid choice. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for serious performance applications. JE Pistons has been in the game for over 75 years, and they build these kits specifically for each engine to give you the best balance of durability and power.

What sets these pistons apart is their advanced design. They feature JE's proprietary Forged Side Relief (FSR) forging, which helps reduce friction and save weight by using a shorter wrist pin and a narrower skirt. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and more consistent power. Some applications also include a skirt coating that further cuts down on friction and wear, while also making the engine run a bit quieter. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have everything you need to get started.

This set is designed for an 84mm bore and a 9.5:1 compression ratio, making it suitable for many performance builds. It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
