About this part

Product Details

Starting with domestic 2618 alloy forgings, these Manley pistons are built for serious performance in your 2015+ Subaru WRX with the FA20F engine. The 86mm standard bore size and 10:1 compression dish are designed to work with your engine's specifications, aiming for improved power output and reliability when you're pushing the limits.

Manley puts a lot of thought into how these pistons interact with the cylinder walls. They feature proven cam and barrel skirt profiles that help generate power while also being gentle on the cylinder walls, reducing wear over time. The ring lands and grooves are machined to strict standards, which is key for getting a good seal from your piston rings, ultimately translating to more power. Each piston also comes with premium chrome moly wrist pins, and Manley's unique fixturing process ensures the ring grooves are perfectly square to the skirt, a detail that matters for consistent performance.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. If you're rebuilding the top end of your FA20F engine, these pistons are a solid option from a well-known name in performance engine components.
