Wiseco Ford Duratec 2.3L 87.5mm Bore 12.4:1 CR Pistons (Inc Rings)

If you're building a high-performance Duratec 2.3L engine for serious racing or severe duty applications, these Wiseco forged pistons are a solid choice. They're designed to handle the extreme pressures and temperatures that come with pushing an engine hard, offering a significant upgrade over stock components. With a 12.4:1 compression ratio, they're intended for builds where maximum power output is the goal.

Wiseco machines these pistons from 2618 aluminum right here in the USA, which gives them improved tensile strength for better durability under stress. They feature precision ring grooves, an anti-detonation groove, and other features to ensure a good seal and prevent detonation. The piston crowns are fully machined for a clean combustion chamber surface, and they also come with a special ArmorGlide skirt coating. This coating helps reduce friction, resist seizure, and operate more quietly, which is a nice touch for a racing component.

This set includes the pistons, premium rings, and features forced pin oiling to keep the wrist pins well-lubricated. They are designed to fit a range of Ford, Mazda, and Mercury vehicles with the 2.3L Duratec or MZR engine, including popular models like the Ford Focus, Mazda 3, and Mercury Mariner. Keep in mind these are not CARB approved and cannot be shipped to California.
