CP Piston & Ring Set for Hyundai Genesis Coupe G4KF Theta II Bore (86.0mm) - Size (Std) - CR (9.0)

If you're rebuilding the engine in your Hyundai Genesis Coupe with the G4KF Theta II engine, especially for performance applications, a solid set of pistons is crucial. This standard bore (86.0mm) piston and ring set from CP Pistons is built for the demands of a performance engine build. With a 9.0:1 compression ratio, these pistons are designed to work well with various tuning setups, offering a good balance for both naturally aspirated and forced induction builds.

CP Pistons are well-known in the performance world for their robust construction. These pistons are forged from high-strength aluminum alloy, which makes them incredibly durable and able to withstand the higher cylinder pressures and temperatures that come with performance tuning. The standard bore size means they're a direct replacement for your original pistons if your engine block is still within spec, simplifying the rebuild process. The included rings are also selected to ensure a proper seal and optimal performance within the cylinder.

When undertaking an engine rebuild of this caliber, it's important to ensure all components are properly matched. This set is designed for the G4KF Theta II engine, but remember that it is not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation guidelines for the best results during your build.
