JE Pistons AUDI 1.8T 9.25:1 KIT Set of 4 Pistons

Forged from 2618 aluminum, these JE Pistons are built to handle the demands of a performance Audi 1.8T engine. This kit includes four pistons, designed specifically for the 1.8T 20V engine, featuring an inverted dome/dish to achieve a 9.25:1 compression ratio. This compression level is a popular choice for enthusiasts looking for a balance between street drivability and enhanced performance, especially when paired with modifications like turbo upgrades.

JE Pistons brings over 75 years of experience to their manufacturing process, with these pistons being forged and machined entirely in the USA. They incorporate a proprietary Forged Side Relief (FSR) design, which reduces skirt width and uses a shorter wrist pin to minimize friction and save weight. Depending on the specific application, these pistons may also feature an accumulator groove to help control combustion gas pressure, improving ring seal and maintaining consistent power. A skirt coating, also application-dependent, further reduces friction and wear on the cylinder walls, contributing to quieter operation.

This kit comes complete with high-quality wrist pins, locks, and JE Pro Seal premium piston rings, ensuring you have the essential components for installation. While these pistons are designed for optimal performance and durability in high-demand applications, please note they are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
