Product Details

If you're rebuilding the top end of your Ford 5.0L Coyote Gen 3 engine from 2018 and newer, these Mahle MS pistons are a solid choice. This set is designed for direct injection applications and is built to handle the demands of a performance engine build. They come in a set of 8, ready to be installed in your 308 cubic inch engine.

Mahle uses 2618 aluminum for these pistons, a well-known material in performance engine building for its strength and durability under high temperatures and pressures. The pistons feature a 93.015mm bore and a compression height of 1.167 inches, with a dish volume of -1.5cc. This configuration results in a 10.4:1 compression ratio when paired with a 3.650-inch stroke and a 5.933-inch connecting rod, which is a common setup for these Coyote engines. The pin diameter is 0.866 inches. Each piston weighs in at 383 grams, helping to keep reciprocating mass manageable for improved engine response.

It's important to note that these pistons are not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures, especially regarding ring installation and piston-to-wall clearance, which are critical for engine longevity.
