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

If you're rebuilding the engine in your 2002-2006 Acura RSX for serious performance, this Wiseco forged piston set is a solid choice. These aren't your average pistons; they're designed for demanding race applications where durability and strength are critical. Wiseco builds these with a -9cc dish and a strutted design, specifically for the K20A engine, with a bore size of 86.50mm. They are made from 2618 aluminum, which offers improved tensile strength for high-stress environments.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve overall ring seal. The crown is also fully machined for a clean, consistent surface. For reduced friction and quieter operation, these pistons come with an ArmorGlide skirt coating, which also helps prevent seizing. Plus, they feature forced pin oiling to ensure the wrist pins stay well-lubricated under extreme conditions.

This kit includes everything you need for a set of four cylinders, ready for your high-performance build. 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.
