Supertech Ford/Mazda 2.3L 88mm Bore -6cc Dome 11:1 CR Pistons - Set of 4 (Excl Rings)

This set includes four Supertech forged pistons, each with an 88mm bore and a -6cc dome that helps achieve an 11:1 compression ratio. These pistons are specifically made for Ford and Mazda 2.3L engines and are designed to be a direct replacement for your stock pistons, though they do not include piston rings. If you're rebuilding the top end of your 2.3L engine and looking to increase compression for improved performance, these pistons are a solid choice.

Forged from high-strength aluminum alloy, these pistons are built to withstand the increased pressures and temperatures associated with a higher compression ratio. The -6cc dome shape is carefully engineered to work with specific cylinder head volumes to achieve the target 11:1 compression, which can lead to a noticeable increase in power and throttle response when paired with appropriate tuning. The 88mm bore size is standard for many 2.3L applications, ensuring a proper fit within the cylinder walls. Remember that installing new pistons often requires cylinder honing and careful measurement to ensure proper clearance and longevity.

When undertaking an engine rebuild with these pistons, it's important to have the correct supporting components. You will need to purchase a separate set of piston rings that are compatible with the 88mm bore and the piston groove dimensions. Additionally, proper balancing of the rotating assembly, including these new pistons, is crucial for smooth engine operation and to prevent premature wear. Always refer to the manufacturer's installation instructions for precise details on clearance, ring gap, and assembly procedures to ensure a successful rebuild.
