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

If you're rebuilding the engine in your 2007-2013 Mazda 3 for serious performance, these Wiseco forged pistons are a solid choice. They're designed to handle the stress of heavy-duty and severe-duty applications, giving you the confidence to push your engine further.

These pistons are made from 2618 aluminum, which is known for its strength, and are forged and machined right here in the USA. They feature precision ring grooves, anti-detonation grooves, and a special skirt coating called ArmorGlide. This coating helps reduce friction, resist seizing, and even makes the engine run a bit quieter. The fully machined crown also ensures a clean, consistent surface for combustion.

This set is for a single piston with a dished crown, resulting in a 9.5:1 compression ratio. They use a 0.886 inch pin diameter and have forced pin oiling to keep things well-lubricated under high stress.
