Mahle MS 14-15 Cobra Jet Piston Set 316ci 3.710in Bore 3.650 Stroke -8.8cc 9.9 CR Set of 8

What you get in this Mahle set are eight forged pistons, designed specifically for the NHRA-legal Ford 5.0L Modular 4-valve engine found in the 2014 and 2015 Cobra Jet models. These pistons are built to handle the demands of high-performance racing applications, with a 316 cubic inch displacement, a 3.710 inch bore, and a 3.650 inch stroke. The -8.8cc valve relief volume and 9.9:1 compression ratio are key figures for tuning your engine's performance.

Mahle uses 2618 aluminum for these pistons, a strong and durable material commonly chosen for racing applications because of its excellent strength-to-weight ratio and ability to withstand high temperatures and pressures. Each piston weighs in at 375 grams, contributing to a well-balanced rotating assembly. The 1.167 inch compression height and 5.933 inch rod length are critical dimensions that ensure proper geometry within the engine, working in conjunction with the 0.866 inch wrist pin for reliable operation under extreme conditions.

Keep in mind that these pistons are not CARB approved and therefore cannot be shipped to California. For builders working on a Ford Coyote 316 cubic inch engine, this Mahle piston set offers a well-built foundation for a powerful build.
