JE Pistons Acura K20 86.25mm Bore CR 9.25.1 KIT Set of 4 Pistons

If you're rebuilding the engine in your Acura K20 for serious performance, a set of JE Pistons is a solid choice. These aren't just any pistons; they're forged from 2618 aluminum right here in the USA, giving them the high tensile strength needed for demanding applications where stock parts just won't cut it. With a bore of 86.25mm and a compression ratio of 9.25:1, they're designed to work with your specific K20 engine setup to help you get the most out of your build.

JE Pistons brings over 75 years of experience to the table, and you can see it in the details. They use a proprietary Forged Side Relief (FSR) forging design that helps reduce friction and skirt wear, saving weight and potentially improving power. Depending on the specific application, you might also find an accumulator groove to help reduce combustion gas pressure and improve ring seal, along with a skirt coating to further cut down on friction and noise. This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components ready for installation.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures when working on your engine.
