Supertech Honda K24 w/K20 Head 87.5mm Bore -0.5cc Dish 11.5:1 CR Pistons - Set of 4 (Excl Rings)

These Supertech pistons are forged from high-strength aluminum alloy, a material chosen for its excellent strength-to-weight ratio, making them a solid choice for high-performance K-series Honda engines. Specifically designed for K24 blocks fitted with a K20 cylinder head, these pistons feature an 87.5mm bore and a -0.5cc dish volume, which helps achieve a 11.5:1 compression ratio when paired with the correct head gasket and K20 head. This compression level is well-suited for naturally aspirated builds aiming for improved power output, or for boosted applications where careful tuning is applied.

The forged construction means these pistons are significantly stronger and more durable than cast pistons, allowing them to withstand the higher cylinder pressures and temperatures common in performance applications. The precise dish volume and bore size are critical for achieving the target compression ratio and ensuring proper piston-to-wall clearance, which is essential for engine longevity and performance. Remember that these pistons are sold as a set of four and do not include piston rings, so you'll need to source those separately to complete the assembly.

When rebuilding or modifying your K-series engine, selecting pistons that are built to handle increased stress is key. These Supertech pistons offer a well-built option for enthusiasts looking to optimize their engine's performance. It's important to note that these pistons are not CARB approved and cannot be shipped to California.
