Supertech Mazda Miata 1.6L 79.0 mm Bore -10.5cc Dish 8.8:1 CR Pistons - Set of 4 (Excl Rings)

Supertech forged pistons for your Mazda Miata 1.6L engine. This set is designed for a 79.0 mm bore and features a -10.5cc dish, resulting in a compression ratio of 8.8:1. These pistons are a solid choice if you're rebuilding your engine and looking for a reliable component that can handle increased stress, especially if you plan on forced induction or higher performance applications. They are sold as a set of four, but remember that piston rings are not included and will need to be purchased separately.

Crafted from high-strength aluminum, these pistons are forged, meaning the material is heated and shaped under pressure. This process creates a denser, stronger grain structure compared to cast pistons, making them more resistant to detonation and fatigue. The 8.8:1 compression ratio is a good balance for many performance builds, offering a noticeable increase in power potential without being overly sensitive to fuel quality, especially when paired with modifications like a turbocharger or supercharger. The -10.5cc dish helps achieve this specific compression ratio, which is crucial for tuning and engine performance.

When installing these pistons, it's important to follow the manufacturer's recommended clearances and lubrication procedures. Because these are forged pistons, they often require specific ring sets and careful attention to bore sizing during machining. Ensure you have the correct tools and knowledge for an engine rebuild, or consult with a professional mechanic. This set is not CARB approved and cannot be shipped to California.
