Supertech Ford Duratec 2.0L/2.3L 88.5mm +6.1cc Dome 12.6:1/14.1:1 CR Piston - Set of 4 (Excl Rings)

This is a set of four Supertech forged pistons designed for Ford Duratec 2.0L and 2.3L engines. Each piston features a +6.1cc dome, which helps achieve a compression ratio of either 12.6:1 or 14.1:1, depending on your cylinder head volume. These pistons are built to handle the demands of performance builds and are a solid choice for anyone looking to increase their engine's power output. They are machined to an 88.5mm bore size, which is a common upgrade size for these engines.

Forged pistons are significantly stronger than cast pistons, making them ideal for higher performance applications where increased cylinder pressures are expected. This strength comes from the manufacturing process, where the aluminum is heated and then forced into shape under extreme pressure. The dome design on these specific pistons is engineered to optimize combustion and contribute to the higher compression ratios. It's important to note that this set does not include piston rings, so you will need to source those separately to complete the installation.

When rebuilding or modifying your Duratec engine, choosing the right internal components is crucial for reliability and performance. These Supertech pistons are a well-built option for those aiming for a noticeable increase in horsepower and torque. Always ensure you consult your engine builder or a trusted mechanic for proper installation procedures and to confirm compatibility with your specific cylinder head and camshaft combination, as these factors will influence the final compression ratio.
