Wiseco MAZDA MIATA 1.8L 4v 10.5:1 84.0MM Piston Shelf Stock

If you're rebuilding the engine in your 1999-2005 Mazda Miata, especially for performance applications, a solid set of pistons is key. These Wiseco Professional Series pistons are forged from 2618 aluminum, a material known for its improved tensile strength, making them well-suited for heavy-duty use.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves, anti-detonation features, and enhanced ring seal to ensure reliable performance. They also come with an ArmorGlide skirt coating, which helps reduce friction, resist seizure, and operate more quietly. The fully machined crown is another detail that contributes to their robust construction, designed to handle demanding performance builds.

These pistons are designed for a 84.00 mm bore and feature forced pin oiling for better lubrication. While they are built for severe duty, remember they are not CARB approved and cannot be shipped to California.
