Wiseco Volkswagen Golf/Jetta 1.8L 8V Head 82.5mm Bore 9.5:1 CR Piston Kit - Set of 4

When you're rebuilding the top end of your 1984-1992 Volkswagen Jetta or Golf with the 1.8L 8V engine, this set of four forged pistons from Wiseco is a solid choice. These pistons are designed to handle serious performance applications, offering improved strength and durability over stock components. They feature an 82.5mm bore and a 9.5:1 compression ratio, making them suitable for builds that demand more from the engine.

Wiseco crafts these pistons from 2618 aluminum right here in the USA, which gives them better tensile strength for high-stress situations. You'll find precision ring grooves, anti-detonation features, and extra sealing improvements to ensure a good seal and prevent issues like detonation. They also come with an ArmorGlide skirt coating that helps reduce friction, make operation quieter, and resist seizing. The fully machined crown and forced pin oiling are details that show these are built for heavy-duty performance.

This kit includes everything you need to replace the pistons on your 1.8L 8V engine, with a compression height of 32.15mm and a pin diameter of 0.787 inches. Keep in mind 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.
