The Manley Platinum Series 37cc dish piston set for BMW N55/S55 engines is a forged piston solution aimed at professional engine builders and tuners seeking durable, high-quality pistons for boosted applications. These pistons use domestic 2618 alloy forgings, proven cam-and-barrel skirt profiles, and tool steel wrist pins. Exact ring lands and grooves plus moly skirt coatings on select part numbers improve ring seal and protect cylinder walls for long-term use.
