Supertech Ford Duratec 2.3L 89.5mm -20cc Dish 9.3:1 CR Forged Piston Set of 4 (Excl. Rings)
The Supertech forged piston set, engineered for reliable power and durability in high-stress applications. These pistons feature an 89.5mm bore, 1.122-inch compression height, and -20cc dish volume to achieve a 9.3:1 compression ratio, balancing efficiency and boost readiness. Crafted in Argentina using European-sourced technology, they withstand up to 42 psi of boost when paired with alcohol fuels, delivering consistent performance that outpaces stock components in endurance and heat management.
The 4032 aluminum alloy, enhanced with copper, nickel, and magnesium, reduces thermal expansion while improving wear resistance and conductivity, making this set a direct fit for turbocharged or naturally aspirated setups requiring robust internals.
Compared to factory pistons or basic aftermarket alternatives, Supertech's design incorporates contact reduction grooves, an undercut ring land, and phosphate coating for smoother operation and reduced friction resulting in longer service life and fewer failures under load. This makes them the practical pick for racers and daily drivers alike, ensuring your Duratec 2.3L handles increased displacement or forced induction without the vulnerabilities of lesser materials.
