If you're rebuilding the engine in your Ford Focus ST 2.0L EcoBoost, a strong set of pistons is crucial for handling increased boost and power. This set of four forged pistons from CP Pistons is built to withstand the demands of a performance-oriented 2.0L turbocharged engine. They feature a standard bore size of 87.5mm and a compression ratio of 10.0:1, making them a solid choice for builds aiming for improved power while maintaining reliability.

CP Pistons are well-known in the performance world for their robust construction. These pistons are forged from high-strength aluminum alloy, which offers a better strength-to-weight ratio compared to cast pistons. This forging process aligns the grain structure of the metal, making them exceptionally resistant to detonation and the high cylinder pressures common in turbocharged applications. The 10.0:1 compression ratio is a popular target for tuners, offering a good balance between power output and pump gas drivability. Each piston in this set is precision-machined to ensure a consistent fit and performance across all cylinders.

This set includes the pistons and the necessary rings to get your engine back together. Remember that this piston set is not CARB approved and cannot be shipped to California. For optimal performance and longevity, it's always recommended to consult with your engine builder or refer to CP Pistons' installation guidelines for proper assembly and break-in procedures.
