What is the purpose of the ArmorGlide skirt coating?

The ArmorGlide skirt coating on these Wiseco pistons is designed to reduce friction between the piston and cylinder wall. This helps prevent seizure and contributes to quieter engine operation.

Are these pistons suitable for a street-driven car?

These pistons are part of Wiseco's Professional Series, designed and built for heavy to severe duty race builds. While they can be used in high-performance street applications, they are engineered for demanding use.

What does the -18.5cc dish volume mean for my engine?

The -18.5cc dish volume refers to the shape of the piston crown. This specific dish helps to achieve a desired compression ratio when paired with the correct cylinder head and gasket combination for your S52 engine build.

Product Details

If you're rebuilding the engine in your BMW S52 3.2L and looking for serious performance, this set of six forged pistons from Wiseco is a solid choice. These pistons are made from 2618 aluminum, which is known for its strength, and are forged and machined right here in the USA. They feature precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal, which is crucial for keeping combustion pressure where it belongs.

Wiseco also includes an ArmorGlide skirt coating on these pistons. This coating helps reduce friction, resist seizure, and even makes the engine run a bit quieter. The fully machined crown and forced pin oiling are details that show these pistons are built to handle the demands of heavy to severe duty racing applications. They have a dish volume of -18.5cc and a bore size of 87.00mm, with a 31mm compression height.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance engine for racing or severe duty, these Wiseco pistons are designed to help you remove your limits.
