Wiseco Alfa Romeo AR3055-33 87.5mm Bore (+.5mm) 10:1 CR Pistons (Inc Rings)

This is a set of four forged pistons from Wiseco, specifically made for Alfa Romeo 1.7L engines. You get the pistons themselves, which are 87.5mm in bore size and have a 10:1 compression ratio, along with the necessary rings to complete the assembly. These are built for serious racing and heavy-duty applications where durability and performance are critical.

Wiseco crafts these pistons from 2618 aluminum, a material chosen for its improved tensile strength, making them well-suited for the demands of severe duty. The machining process includes precision ring grooves, anti-detonation features, and other enhancements designed to improve ring seal and overall performance. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and longer life. The fully machined crown and forced pin oiling further demonstrate the attention to detail in their construction for high-stress environments.

Because these are designed for demanding performance builds, it's important to note they are not CARB approved and cannot be shipped to California. Ensure you consult the manufacturer's installation instructions for proper fitment and assembly procedures.
