Mahle MS Piston Set Ford Cobra Jet 343ci 3.622in Bore 4.165 Stroke 6.657 Rod .866 Pin -12.6cc

If you're building a high-performance Ford Cobra Jet engine, especially for NHRA legal applications, a solid set of pistons is where you start. This Mahle MS Piston Set is built for the Ford Modular 5.4L 4-valve engines found in the 2008, 2010, and 2012 Cobra Jet models, and is also suitable for 330 cubic inch Ford Mod 2V/4V applications.

These are forged pistons, which means they're made from a solid block of aluminum that's heated and hammered into shape. This process creates a much stronger and more durable piston than cast aluminum, able to withstand the higher cylinder pressures and temperatures of a performance engine. This set features a 3.622-inch bore, a 4.165-inch stroke, and a 6.657-inch connecting rod length, with a 0.866-inch pin. The -12.6cc dish volume contributes to the compression ratio, and the pistons weigh in at 364 grams each. They are designed to fit right into your existing engine build, assuming the correct bore and stroke are being used.

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 details, especially when dealing with performance engine components. This set is a well-built foundation for a powerful engine build.
