Wiseco Acura 4v R/DME -9cc STRUTTED 86.5MM Piston Shelf Stock

If you're working on a performance build for your 2002-2006 Acura RSX, this Wiseco piston is a solid choice. It's a shelf stock replacement designed for the K20 engine, with a bore size of 86.50 mm. These pistons are made from 2618 aluminum, which is known for its improved tensile strength, making them well-suited for demanding applications where durability is key.

Wiseco builds these pistons with features like precision ring grooves, anti-detonation grooves, and enhanced ring sealing to help ensure a good seal and prevent issues under high stress. They also come with an ArmorGlide skirt coating that helps reduce friction and noise, while also resisting seizure. The crown is fully machined, and the design includes forced pin oiling to keep the wrist pin lubricated. These are intended for heavy to severe duty race builds, so you know they're built tough.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. It's sold individually, so you'll need to order the correct quantity for your engine.
