Manley BMW N54B30 32cc Platinum Series Dish Extreme Duty Piston Set - 84.5mm Bore

This is a set of Manley Platinum Series pistons designed for BMW N54B30 engines. You get six pistons, each with a 32cc dish volume and a bore size of 84.5mm. These pistons are built using Manley's signature 2618 alloy forgings, which are known for their strength and ability to handle high performance demands. They also feature proven cam and barrel skirt profiles, tool steel wrist pins, and a moly skirt coating to help reduce friction and wear.

Manley puts a lot of attention into the details that matter for engine building. The ring lands and grooves are machined to very strict standards, which helps ensure a better seal from your piston rings, leading to more power. The cam and barrel profiles on the skirts are designed to be effective at generating power while also being easy on your cylinder walls during operation. This is achieved through unique fixturing that allows the skirt to be turned and the ring grooves to be machined in the same setup, ensuring the grooves are perfectly square to the skirt.

These pistons are a solid choice for anyone rebuilding or significantly upgrading their N54 engine. They come with premium chrome moly wrist pins, and Manley offers upgrades to even stronger alloys if your build requires it. Keep in mind that these are not CARB approved and cannot be shipped to California. For installation, always refer to the manufacturer's detailed instructions to ensure proper fitment and performance.
