JE Pistons ACURA K24/K20 KIT Set of 4 Pistons

If you're rebuilding the engine in your Acura K24 or K20 for serious performance, a strong set of pistons is where you start. JE Pistons has been making forged pistons for over 75 years, and this kit is built specifically for those high-demand applications. They're forged and machined right here in the USA using 2618 aluminum, which gives them the high tensile strength needed to handle the extra stress of performance builds.

What sets these apart is JE's proprietary Forged Side Relief (FSR) design. This means they've worked to minimize friction and skirt wear, which not only helps with durability but also saves a bit of weight. Some applications also get an accumulator groove to help reduce combustion gas pressure, leading to better ring seal and more consistent power. Plus, many of these pistons come with a skirt coating to further reduce friction and noise. This kit includes everything you need to get them installed: high-quality wrist pins, locks, and JE Pro Seal premium piston rings.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For any performance engine build, using pistons designed specifically for your engine and intended use is key to achieving both durability and the performance you're looking for.
