Product Description

The Wiseco **KE119M85** piston kit is designed specifically for high-performance rebuilds of BMW's M52B28 2.8 L 24-valve inline-6 engine, used in the 328i/328is and 528i models. With a +1.00 mm oversize bore (85.00 mm) and a deep dish profile (~-23 cc), this kit supports lower compression (~8:1) and is ideal for turbocharged or high-output naturally aspirated builds.

Crafted from forged 2618 aluminum and finished with ArmorGlide® coated skirts, the KE119M85 offers excellent durability, reduced friction, and high-RPM stability. The strutted forging further reinforces key high-stress areas, making the kit suitable for aggressive duty.

The complete kit includes everything required for a full rotating assembly upgrade: six forged pistons, wrist pins, circlips, and a performance ring set. It's an excellent choice for engine builders seeking a reliable, high-performance foundation on the M52B28 platform.
