About this part

Product Details

If you're rebuilding the engine in your BMW N55 or S55, a solid set of pistons is crucial for handling increased power and ensuring long-term reliability. This Manley Platinum Series dish piston set is built for those demanding applications, featuring a 37cc dish volume and an 84.5mm bore size, designed to work with specific engine configurations.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their exceptional strength and ability to withstand high temperatures and pressures common in performance builds. The pistons also feature proven cam and barrel skirt profiles that help generate substantial power while minimizing wear on your cylinder walls. You'll also find exacting standards applied to the ring lands and grooves, which is key for achieving a better ring seal and unlocking more power from your engine. These pistons come with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt for optimal performance.

When building a high-performance engine, attention to detail makes all the difference. This set is a popular choice among professional engine builders and tuners who depend on Manley for durable and powerful components. Please note that this piston set is not CARB approved and cannot be shipped to California. It's always a good idea to consult with your engine builder or refer to Manley's installation guidelines for specific details regarding compatibility and assembly.
