Wiseco Audi RS4 2.7L 30V V6 Bore (82mm) - Size (+0.040) - CR (8.0:1) Pistons Build on Demand

If you're rebuilding the engine in your Audi RS4 2.7L 30V V6, especially if you're aiming for more power or need to replace worn components, a solid set of pistons is fundamental. These Wiseco pistons are built for that purpose, designed to handle the demands of a performance-oriented engine build. They are forged from high-strength aluminum, a process that creates a denser, more durable piston than cast alternatives, making them ideal for higher compression or boosted applications.

This specific set is sized at 82mm with a +0.040 inch undersize, meaning they are intended for a cylinder bore that has been machined to accommodate this size. The compression ratio is set at 8.0:1, which is lower than stock, making these pistons a good choice if you plan on adding a turbocharger or supercharger, as the lower compression helps prevent detonation under boost. Wiseco is well-known for its forged pistons, and this set reflects their commitment to producing reliable engine components. They are built to fit right into your engine block after the necessary machining has been performed.

When undertaking an engine rebuild of this caliber, it's important to ensure all supporting components are up to the task. These pistons are a critical part of the rotating assembly, and their robust construction is designed to work with performance camshafts, upgraded fuel systems, and forced induction setups. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or mechanic for specific recommendations regarding your build and ensure all necessary machining is performed by a qualified professional before installation.
