Supertech Honda K24 Series 89.0mm (+2) 1.181in CH +8cc Dome 13.2:1 CR Piston - Set of 4 (Excl Rings)

This is a set of four Supertech forged pistons designed for Honda K24 engines. You get the pistons themselves, ready to be installed with your own rings. These pistons are built to handle higher compression ratios, specifically 13.2:1, which is a notable increase over stock. This setup is popular for builds aiming for improved performance and power, especially when paired with other engine modifications.

Each piston features an 89.0mm bore size, which is a 2mm overbore compared to the standard K24 bore. The compression height (CH) is 1.181 inches, and the piston dome has a volume of +8cc. This combination is what allows for the increased 13.2:1 compression ratio. Supertech uses forged aluminum for these pistons, a strong material choice that offers good durability under the stresses of higher compression and performance tuning. Because they are forged, they are generally more resistant to detonation and fatigue than cast pistons.

Keep in mind that these pistons are sold without piston rings, so you'll need to source those separately to complete the assembly. Also, these pistons are not CARB approved and cannot be shipped to California. If you're building a high-performance K24 engine, these pistons are a solid option for increasing displacement and compression.
