JE Pistons ACURA K20 9:1 86MKIT Set of 4 Pistons

JE Pistons has been a leader in forged racing pistons for over 75 years, and they bring that experience to their performance pistons for import engines. This set is specifically made for the Acura K20 engine, giving you a 9:1 compression ratio with an inverted dome/dish design. They're forged in the USA using 2618 aluminum, which is strong enough for high-demand performance applications where durability is key.

What sets these pistons apart is their advanced design features. The proprietary Forged Side Relief (FSR) forging design helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, which also saves weight. Depending on the specific application, you might also find an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power. Some applications also include a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also cutting down on operating noise. These pistons are designed specifically for the K20 engine, optimizing performance and durability.

This kit includes everything you need to get these pistons installed: high-quality wrist pins, locks, and JE's Pro Seal premium piston rings. Remember, these pistons are not CARB approved and cannot be shipped to California. They are made 100% in the USA, ensuring a well-built product ready for serious performance.
