JE Pistons Acura K24A w/ K20A Head 87.0mm Bore 14.2:1 CR 12.4cc Dome Piston Kit (Set of 4)

If you're rebuilding the engine in your Acura K24A with a K20A head for serious performance, a strong set of pistons is crucial. This JE Pistons kit is built to handle the demands of a high-compression, high-performance build. These aren't your average pistons; they're forged from 2618 aluminum, a material known for its high tensile strength, making it well-suited for engines pushed to their limits.

JE Pistons has been making performance pistons for a long time, and they build these right here in the USA. They use a proprietary Forged Side Relief (FSR) design, which helps reduce friction and weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, you might also find an accumulator groove to help manage combustion pressure and improve ring seal, and a skirt coating to cut down on friction and noise. This kit comes complete with high-quality wrist pins, locks, and JE's Pro Seal premium piston rings, so you have the essential components for a solid engine build.

This set is designed for an 87.0mm bore and features a 14.2:1 compression ratio with a 12.4cc dome volume, intended for engines built for maximum output. Keep in mind that these pistons are not CARB approved and cannot be shipped to California.
