Wiseco Mazda Speed 3 Dished -13.3cc 9.5:1 Piston Shelf Stock Kit

Wiseco is known for making well-built engine components for demanding applications. If you're building a high-performance Mazda 3, their Professional Series forged pistons are designed to handle serious power. These pistons are built from 2618 aluminum, which gives them improved tensile strength for the stresses of racing and heavy-duty use. They are forged and machined right here in the USA.

You'll find precision ring grooves, an anti-detonation groove, and other features designed to improve ring seal, which is crucial for keeping combustion pressure where it belongs. The piston crown is fully machined, and they feature forced pin oiling for better lubrication. Plus, the ArmorGlide skirt coating helps reduce friction and noise, while also resisting seizure. These are intended for heavy to severe duty performance builds where reliability is key.

This kit includes a set of four pistons, each with a dished crown creating a -13.3cc volume, resulting in a 9.5:1 compression ratio with the stock 2.3L DISI engine. The bore is 88.00 mm, and the compression height is 32.25 mm, with a 0.886 inch pin diameter. Please note that these are not CARB approved and cannot be shipped to California.
