JE Pistons BMW S54B32 12.5 KIT Set of 6 Pistons

If you're rebuilding the engine in your 2001-2006 BMW M3, consider this set of forged pistons from JE Pistons. These pistons are built for the S54B32 engine and feature a 12.5:1 compression ratio, which can help increase power output when paired with appropriate tuning and supporting modifications. JE Pistons has been making high-performance pistons for over 75 years, and these are engineered specifically for your M3's demanding application.

Crafted from 2618 aluminum right here in the USA, these pistons are well-built to handle the stresses of a high-performance engine. They incorporate JE's proprietary Forged Side Relief (FSR) design, which helps reduce friction and skirt wear while also saving weight. An accumulator groove is included, depending on the application, to help improve ring seal and maintain consistent power. Some applications also feature a skirt coating to further reduce friction and noise.

This kit comes complete with everything you need to get your engine back together: six forged pistons, high-quality wrist pins, locks, and JE Pro Seal premium piston rings. Remember that these pistons are not CARB approved and cannot be shipped to California. For optimal performance, ensure you consult with a professional tuner to adjust your engine's calibration after installation.
