Wiseco BMW S52/B32 3.2L 87.00mm Bore 31mm CH -2.7cc Piston (Set of 6)

This set includes six forged pistons for your BMW S52/B32 3.2L engine. These pistons are built with a specific 87.00mm bore and a 31mm compression height, featuring a -2.7cc dish volume. They are designed for builders who are serious about performance and durability, intended for heavy to severe duty race applications where reliability under extreme conditions is paramount.

Wiseco crafts these pistons from 2618 aluminum, chosen for its improved tensile strength, making them well-suited for the demands of high-performance engines. The machining process is meticulous, including precision ring grooves, an anti-detonation groove, and features that enhance ring seal for better combustion efficiency. They also come with an ArmorGlide skirt coating, which helps resist seizure, reduces friction, and contributes to quieter operation. The fully machined crown and forced pin oiling further support longevity and performance in demanding builds.

When rebuilding the top end of your S52 engine for racing, these pistons are a solid option. Keep in mind that these are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
