Manley 02+ Acura RSX (K20A-A2-A3) 86mm STD Bore 12.5:1 Dome Piston - Single

If you're rebuilding the engine in your 2002-2006 Acura RSX, especially if you're aiming for more power, consider these forged dome pistons from Manley Performance. These are designed for the K20A, A2, and A3 engines, with a standard 86mm bore and a 12.5:1 compression ratio, which will raise compression over stock. Manley uses domestic 2618 alloy forgings, a strong material that holds up well under the demands of performance engines. They also feature proven cam and barrel skirt profiles, which help generate power while being easier on your cylinder walls during operation.

The ring lands and grooves are machined to strict standards to ensure a good seal with your piston rings, helping to put more power to the crankshaft. Manley's unique machining process allows them to turn the skirt and machine the ring grooves in one setup, ensuring the grooves are perfectly square to the skirt. These pistons come with premium chrome moly wrist pins, and Manley offers upgrades to even stronger alloys if your build requires it. This is a single piston; you'll need to order the correct quantity for your engine.
