Supertech Ford/Mazda 2.3L 89.5mm Bore -7cc Dome 11:1 CR Pistons - Set of 4 (Excl Rings)

These Supertech pistons are forged from high-strength aluminum, a common choice for performance engine builds because it offers a good balance of strength and weight. The -7cc dome volume combined with the 89.5mm bore size is designed to achieve an 11:1 compression ratio, which is a notable increase over stock and can help improve power output when paired with appropriate tuning. This set includes four pistons, but remember that the piston rings are sold separately, so you'll need to source those to complete the assembly.

The 89.5mm bore is a specific size that's important to match with your cylinder block. If your block has been bored out previously, you'll want to measure it carefully to ensure this is the correct size. Forged pistons like these are generally more durable and can withstand higher cylinder pressures compared to cast pistons, making them a solid option for builds aiming for increased performance or durability under demanding conditions. The dome shape is carefully sculpted to promote efficient combustion and minimize the risk of detonation.

When rebuilding your engine with these pistons, it's crucial to follow the manufacturer's recommended installation procedures and clearances. Proper balancing of the rotating assembly, including these pistons, crankshaft, and connecting rods, is also essential for engine longevity and smooth operation. Ensure you have the correct piston ring set that matches the bore size and piston type for optimal sealing and performance.
