Manley Subaru EJ25 100mm Bore / 1.209in CD Platinum Series -17cc Dish Piston Set

This Manley Platinum Series piston set includes four forged pistons, each with a -17cc dish, designed for Subaru EJ25 engines with a 100mm bore. These pistons are built using Manley's signature Platinum Series construction, which starts with domestic 2618 alloy forgings known for their strength and performance capabilities. They also come standard with premium chrome moly wrist pins, and feature moly skirt coatings for added durability and reduced friction.

Manley pays close attention to the details that matter for engine building. The ring lands and grooves are machined to exacting standards, which helps ensure a better seal from your piston rings, leading to more power. The pistons also feature proven cam and barrel skirt profiles. This design helps generate substantial power while also being gentle on your cylinder walls, promoting longer engine life. Manley's unique fixturing process allows them to machine the skirt and cut the ring grooves in a single operation. This ensures the ring grooves are perfectly square to the piston skirt, which is critical for proper ring seal and overall engine performance.

This set is not CARB approved and cannot be shipped to California. For professional engine builders and tuners looking for reliable performance and durability, these Manley pistons are a solid choice.
