CP Piston & Ring Set for Ford Duratec 2.0L/2.3L -Bore (87.5mm)-Size (STD)-CR (9.0/10.3)-Set of 4

If you're rebuilding the engine in your 2004-2009 Mazda 3 with the Duratec 2.0L or 2.3L engine, a solid set of pistons is crucial for performance and reliability. This set from CP Pistons is built for those looking to get the most out of their engine, whether it's for daily driving or more spirited use. These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape under immense pressure. This process creates a much stronger and more durable piston than cast ones, which are poured into a mold. Forged pistons can handle higher cylinder pressures and temperatures, making them ideal for rebuilt or performance-oriented engines.

This specific set is designed for a standard bore of 87.5mm, ensuring a precise fit for engines within factory tolerances. The compression ratio is listed at 9.0:1 for naturally aspirated setups and 10.3:1 for forced induction applications, giving you options depending on your build goals. CP Pistons is known for their well-built components, and this set includes the necessary rings to complete the piston assembly. Proper installation is key, and it's recommended to consult your vehicle's service manual or a professional mechanic for the correct procedures, especially when dealing with engine internals.

When you're diving deep into an engine rebuild, using high-quality components like these forged pistons from CP Pistons can make a significant difference in the longevity and performance of your Mazda 3. Remember that this part is not CARB approved and cannot be shipped to California. Always ensure you are using the correct torque specifications and assembly procedures during installation to achieve the best results.
