Manley Platinum Series Dish Pistons w/ Rings 88mm Bore (+5mm) 94mm 9.5:1 CR - Mazda 3 Mazdaspeed 2007-2013 (630005C-4)

Fits 2007-2013 Mazda 3 Mazdaspeed.

Engineered for high-output DISI engines, Manley Platinum Series pistons are designed for professional engine builders who demand superior durability and ring seal. These pistons are machined from high-strength domestic 2618 aluminum alloy forgings and feature a dish-type crown to achieve a 9.5:1 compression ratio. With an 88mm bore (+5mm overbore) and compatibility with a 94mm stroke, this set is built to handle the rigors of increased boost and thermal load.

Manley utilizes a proprietary fixturing process that allows skirt turning and ring groove machining to be completed in a single operation. This ensures ultimate squareness between the ring grooves and the skirt, which is critical for consistent ring seating and oil control. The cam and barrel skirt profiles are specifically engineered to reduce friction and cylinder wall wear while maintaining stability under high cylinder pressures.
