JE Pistons Acura K24/K20 90.0mm Bore 12.5:1 CR 9.0cc Dome Piston Kit (Set of 4 Pistons)

If you're building a high-performance K24 or K20 engine for your Acura, this JE Pistons Piston Kit is a solid choice. These pistons are forged from 2618 aluminum, a material known for its high tensile strength, making them well-suited for the demands of racing and serious performance builds. They're designed with a 90.0mm bore and a 12.5:1 compression ratio, intended to optimize power output for these specific K-series engines.

JE Pistons brings over 75 years of experience to the table, and these pistons are made 100% in the USA. They feature 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 improve ring seal and reduce flutter, and a skirt coating to further cut down on friction, wear, and noise. This kit includes everything you need to get started: the set of four pistons, high-quality wrist pins, locks, and JE's Pro Seal premium piston rings.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For serious K-series engine builds, this kit offers a well-built foundation for significant power gains.
