Supertech 96-00 BMW E36 M3 S52/B32 3.2L 87mm 4032 Forged Piston - Set of 6 (Excl Rings)

Supertech is known for making well-built engine components, and this set of six 87mm 4032 forged pistons is a prime example. These are designed for the 1996-2000 BMW E36 M3 models equipped with the S52 or B32 3.2L engine. If you're rebuilding the top end of your M3 and looking for a strong foundation, these pistons are a solid option.

Forged from 4032 aluminum alloy, these pistons offer a good balance of strength and lighter weight compared to cast pistons. The 4032 alloy is known for its excellent thermal expansion properties, making it suitable for high-performance applications where temperatures can get high. Each piston measures 87mm in bore diameter, which is the standard size for these engines, and they are designed to fit precisely. This set includes six pistons, but remember that piston rings are sold separately, so you'll need to source those to complete the installation.

When rebuilding an engine, especially one like the S52 which is often pushed to its limits, using forged components like these pistons can make a significant difference in durability and reliability. They are built to handle the stresses of increased horsepower and torque, whether you're building a track car or a powerful street machine. Ensure you consult your engine's service manual or a professional mechanic for the correct installation procedures and any additional components needed for your specific build.
