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

If you're rebuilding the engine in your 1994-2005 Mazda Miata, especially for performance or racing applications, these Wiseco Professional Series pistons are a solid choice. This kit includes four pistons, each with an 84.00 mm bore and a 10.5:1 compression ratio, designed to handle the demands of serious engine builds. They are forged from 2618 aluminum right here in the USA, which gives them improved tensile strength compared to cast aluminum, making them well-suited for heavy or severe duty use.

Wiseco has packed these pistons with features to enhance both performance and durability. You'll find precision ring grooves, anti-detonation grooves, and other features designed to improve ring seal. The piston crowns are fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated under high stress. Additionally, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure, which is crucial when pushing an engine hard.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders looking to maximize their Miata's engine potential and ensure long-term reliability under demanding conditions, this Wiseco piston set offers a well-built foundation.
