Manley 02+ Acura RSX (K20A-A2-A3) 86mm STD Bore 11.5:1 Dome Piston Set with Rings

This Manley piston set includes everything you need to get your 2002-2006 Acura RSX engine rebuilt with a higher compression ratio. You get a full set of four forged pistons, each with a 11.5:1 dome compression ratio, along with the necessary piston rings and chrome moly wrist pins. These are designed for the K20A, K20A2, and K20A3 engines, featuring an 86mm standard bore size.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle demanding engine conditions. The pistons feature proven cam and barrel skirt profiles that help generate power while also being gentle on your cylinder walls. They've also paid close attention to the ring lands and grooves, machining them to strict standards to ensure a better ring seal, which translates directly to more power. The unique fixturing Manley uses allows them to machine the skirt and ring grooves in one operation, ensuring they are perfectly square to each other.

This set is a solid choice for anyone rebuilding their RSX engine, whether for performance or to replace worn-out components. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
