Manley 02+ Acura RSX (K20A-A2-A3) 86mm STD Bore 9.0:1 Dish Piston Set with Rings

When you're rebuilding the engine in your 2002-2006 Acura RSX, especially if you're aiming for more power or need to replace worn components, this Manley forged piston set is a solid choice. You'll get a complete set of four pistons, each with a 9.0:1 compression dish, designed to fit the standard 86mm bore of your K20A, K20A2, or K20A3 engine. This kit also includes the necessary rings and premium chrome moly wrist pins to get your engine back together.

Manley uses domestic 2618 alloy forgings for these pistons, which are known for their strength and ability to handle higher performance demands compared to cast pistons. They've also incorporated proven cam and barrel skirt profiles that help generate power efficiently while being gentler on your cylinder walls. The ring lands and grooves are machined to strict standards, which is crucial for a good seal and maximizing the power your engine makes. Manley's unique manufacturing process ensures the ring grooves are perfectly square to the piston skirt, contributing to better ring seal and overall engine health.

This set is a popular choice among professional engine builders and tuners who rely on Manley for dependable performance. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a complete rebuild, you'll want to ensure you have all the necessary gaskets, seals, and other components ready to go.
