CP Piston & Ring Set for Ford Duratec 2.0L/2.3L -Bore (88.0mm)-Size (+0.5mm)-CR (10.3)-Set of 4

CP Pistons is well-known for building strong, reliable engine components for performance applications. If you're rebuilding the engine in your 2004-2009 Mazda 3, especially if you're looking to get more out of your Ford Duratec 2.0L or 2.3L engine, this piston and ring set is a solid choice. These aren't just stock replacements; they're forged pistons designed to handle more stress and heat than cast pistons, making them ideal for builds where durability and performance are key.

This set includes four pistons and rings, all measuring 88.0mm in bore size and are a 0.5mm oversize. The compression ratio is set at 10.3:1, which is a notable increase over stock and can contribute to improved power output when paired with appropriate tuning. The forged construction means these pistons are made from a solid block of aluminum that's heated and hammered into shape, giving them a much stronger grain structure and resistance to deformation under high cylinder pressures. This is crucial for engines that see demanding use or have been modified for increased output.

When you're putting an engine back together, especially one that's been rebuilt or modified, using well-made components like these CP Pistons is important for long-term reliability. This set is designed to fit your 2004-2009 Mazda 3 and the specified Ford Duratec engines. Remember that any engine modification, especially one that changes compression ratio, will likely require proper engine tuning to achieve optimal performance and prevent issues. Please note that this part is not CARB approved and cannot be shipped to California.
