Supertech Honda K24 Series w/K20 Head 87mm Bore +4.5cc Dome 12.5:1 CR Pistons- Set of 4 (Excl Rings)

Supertech is well-known for making performance engine components, and this set of four forged pistons for Honda K24 series engines with K20 heads is a prime example. These pistons are designed to work with an 87mm bore and feature a +4.5cc dome, which helps achieve a 12.5:1 compression ratio. This setup is ideal for builders looking to increase the power output of their K-series engine, whether for track use or a high-performance street build.

Crafted from strong, forged aluminum, these pistons are built to withstand the higher cylinder pressures and temperatures associated with increased compression and performance tuning. The 87mm bore size is a common upgrade for K24 engines, allowing for a slight increase in displacement over stock. The specific dome shape and volume are carefully calculated to achieve the 12.5:1 compression ratio when paired with a K20 cylinder head, a popular combination for K-series enthusiasts seeking a balance of power and pump gas drivability. It's important to note that these pistons are sold as a set of four and do not include piston rings, so you'll need to source those separately.

When installing these pistons, proper engine balancing and machine work are crucial. Ensure your engine builder is aware of the specific compression ratio and bore size to dial in the tune correctly. This set is a solid option for anyone rebuilding or modifying a K24 engine and looking for a reliable, performance-oriented piston solution from a reputable brand.
