Product Details

If you're rebuilding the engine in your 2002-2006 Acura RSX for serious performance, a set of Wiseco Professional Series pistons is a solid choice. These aren't just stock replacements; they're built from the ground up for demanding race applications where reliability under extreme stress is critical. They feature a flat-top design and measure 86.50 mm in bore diameter, ready to handle the power you're aiming for.

Wiseco crafts these pistons from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for the heat and pressure of high-performance engines. The machining is precise, with anti-detonation grooves and features designed to improve ring seal, helping to keep combustion gases contained and power where it belongs. They also come with an ArmorGlide skirt coating that reduces friction and noise, while also resisting seizure. Plus, the forced pin oiling ensures the wrist pins stay well-lubricated, a small but important detail for longevity in severe duty builds.

This kit includes four pistons, along with premium rings, and is designed to fit right into your K20A engine. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in their RSX, this Wiseco piston set is a well-built foundation.
