Supertech Ford / Mazda 2.3L 88mm (+0.5) Bore -20cc Dome Dish Pistons - Set of 4 (Excl Rings)

This set includes four Supertech forged pistons, each featuring an 88mm bore and a -20cc dome dish. These pistons are specifically made for Ford and Mazda 2.3L engines and are sized at +0.5mm over stock bore. Please note that piston rings are not included with this set and must be purchased separately. These are a popular choice for engine rebuilds where increased performance and durability are desired.

Forged pistons like these are constructed from a solid block of aluminum alloy, making them significantly stronger and more resistant to detonation than cast pistons. This strength is crucial for engines that have been modified for higher horsepower or are subjected to demanding use. The -20cc dome dish design is engineered to work with specific compression ratios, often used in forced induction applications or high-compression naturally aspirated builds. The 88mm bore size indicates these are intended for engines that have been bored out by 0.5mm from their original specification, a common practice during an engine overhaul to restore cylinder integrity or increase displacement.

When rebuilding your engine with these pistons, it's important to ensure you have the correct piston rings that match the 88mm bore and the appropriate thickness for the ring lands. Always refer to your engine's specific service manual for proper installation procedures, torque specifications, and any required clearances. Due to their construction and intended use, these pistons are not CARB approved and cannot be shipped to California.
