JE Pistons ACURA K20 10:1 KIT Set of 4 Pistons

Starting with a 2618 aluminum forging, JE Pistons crafts these K20 piston kits with a specific dome design and a 10.00:1 compression ratio, tailored for high-demand performance applications. These pistons are engineered to handle the stress of racing, whether you're on the drift track or the drag strip, offering a proven combination of durability and performance. Each piston features JE's proprietary Forged Side Relief (FSR) design, which helps minimize friction and power loss by reducing skirt width. This design, along with a shorter wrist pin, also contributes to saving weight, making your engine more responsive.

The manufacturing process, done 100% in the USA, ensures a high level of quality control. Depending on the specific application, these pistons may include an accumulator groove to help reduce pressure from combustion gases, which can prevent ring flutter and improve ring seal for more consistent power delivery. Some applications also feature a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also helping to quiet down operating noise. This kit includes high-quality wrist pins, locks, and JE Pro Seal premium piston rings, so you have the essential components for installation.

When rebuilding or upgrading your K20 engine for performance, these JE Pistons offer a solid foundation. They are designed specifically for the engine and intended use, aiming for optimized performance and durability. Please note that these pistons are not CARB approved and cannot be shipped to California.
