JE Pistons Honda K24 Block w/ K20A Head 87mm Bore 12.5:1 CR 5.2cc Dome Piston Set (Set of 4 Pistons)

This JE Pistons kit gives you a complete set of four forged pistons, designed specifically for the Honda K24 block when used with a K20A cylinder head. Each piston features an 87mm bore and a dome shape that results in a 12.5:1 compression ratio, perfect for building a high-performance naturally aspirated or forced induction engine. You also get the necessary high-quality wrist pins, locks, and JE Pro Seal premium piston rings to get your engine rebuilt and running.

JE Pistons has been making forged pistons for over 75 years, and these are made in the USA from 2618 aluminum. This material offers the strong tensile strength needed for demanding performance builds. The design includes their proprietary Forged Side Relief (FSR) forging, which helps reduce friction and save weight by using a narrower skirt and a shorter wrist pin. Depending on the specific application, these pistons may also feature an accumulator groove to improve ring seal and a skirt coating to reduce friction and noise.

This piston set is intended for serious engine builds where durability and performance are critical. Because these are custom-spec pistons for a specific engine combination, it's important to ensure they match your build plans. Please note that this part is not CARB approved and cannot be shipped to California.
