Supertech Ford/Mazda 2.3L 88mm Bore +1.5cc Dome 12.5:1 CR Pistons - Set of 4 (Excl Rings)

Supertech is known for making well-built engine components, and these forged pistons for Ford and Mazda 2.3L engines are a prime example. If you're building or rebuilding a performance engine, these pistons are designed to handle the demands of higher compression and increased power. They feature an 88mm bore and a dome shape that contributes to a 12.5:1 compression ratio, which is a notable bump over stock, giving you more power and responsiveness.

These pistons are forged, meaning they start as a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast ones, making them ideal for applications where reliability under stress is key. The +1.5cc dome volume is specifically calculated to achieve that 12.5:1 compression ratio when paired with the correct cylinder head volume. This set includes four pistons, but remember that the rings are sold separately, so you'll need to source those to complete the assembly.

When installing these pistons, it's crucial to follow the manufacturer's detailed installation instructions. Proper piston-to-wall clearance, ring gap, and lubrication are essential for their longevity and performance. Because these are a performance part designed for higher compression, it's also important to ensure your engine management system is tuned accordingly to take full advantage of the improved breathing and combustion characteristics.
