Supertech Ford Duratec 2.0L/2.3L 88.5mm +0.5cc Dome 12.5:1/11.2:1 CR Piston - Set of 4 (Excl Rings)

Supertech is well-known for making robust engine components, and this set of four forged pistons for Ford Duratec 2.0L and 2.3L engines continues that tradition. These pistons are designed to handle increased performance demands, whether you're rebuilding an engine for a street car or a more serious build. They feature an 88.5mm bore size, which is a +0.5mm overbore from the stock 88.0mm, and a specific dome shape that helps achieve either a 12.5:1 or 11.2:1 compression ratio, depending on your cylinder head volume. This allows for tuning to specific performance goals.

Crafted from strong forged aluminum, these pistons are built to withstand higher cylinder pressures and temperatures compared to cast pistons. The dome design is precisely machined to ensure consistent combustion chamber volume, which is critical for achieving the target compression ratios and optimal engine performance. Because these are a set of four pistons, they are sold without rings, giving you the flexibility to choose the ring set that best suits your build's specific needs and clearances. This approach ensures that every component in your engine assembly is tailored for reliability and performance.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Proper installation is key to realizing their full potential and ensuring long-term durability. Remember that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a trusted mechanic for specific installation guidance and to confirm compatibility with your particular engine configuration and build plan.
