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 built from 2618 aluminum, which offers improved tensile strength, making them well-suited for heavy-duty and severe-duty applications where stock components might not hold up. The pistons feature a dished crown that results in a 9.5:1 compression ratio, a common target for boosted engines that need a balance between power and reliability.

Wiseco machines these pistons in the USA, paying close attention to details like precision ring grooves and anti-detonation features to ensure a good seal and prevent damage. They also come with an ArmorGlide skirt coating, which helps reduce friction and noise while resisting seizure. The crown is fully machined, and the design includes forced pin oiling to keep the wrist pin lubricated under high stress.

This set is for a single piston with an 87.50 mm bore and a 32.26 mm compression height. Remember that these pistons are not CARB approved and cannot be shipped to California.
