Supertech Honda K24 Series w/K20 Head 89mm Bore +2.2cc Dome 12.5:1 CR Pistons- Set of 4 (Excl Rings)

This set includes four Supertech forged pistons designed for Honda K24 series engines when used with a K20 cylinder head. Each piston features an 89mm bore and a +2.2cc dome volume, resulting in a 12.5:1 compression ratio. Please note that piston rings are not included with this set and must be purchased separately.

These pistons are constructed from well-built forged aluminum, a material chosen for its strength and lighter weight compared to cast alternatives. This makes them a solid choice for builds where improved performance and durability are key. The 89mm bore size is a common upgrade for K24 engines, and when paired with a K20 head, it allows for a specific compression ratio tailored for certain performance goals. The 12.5:1 compression ratio is suitable for naturally aspirated builds or those looking for a noticeable increase in power output, though it requires careful tuning and consideration of fuel octane.

When rebuilding or modifying your Honda K-series engine, choosing the right internal components is crucial. These Supertech pistons are designed to handle the demands of a performance-oriented engine. Remember to consult your engine builder or a trusted mechanic for specific installation procedures and recommended supporting modifications to ensure optimal performance and longevity.
