CP Piston for Ford 4.6L - Bore (3.552) - Compression Ratio (9.7:1) - Set of 8

This product is a set of eight forged pistons from CP Pistons, designed for the 2003-2004 Ford Mustang with a 4.6L engine. You get pistons with a 3.552-inch bore and a 9.7:1 compression ratio, which is a common target for builds looking for a balance between power and pump gas drivability.

Forged pistons like these are a strong choice when you're rebuilding or upgrading your engine. They're made from a solid block of material that's heated and hammered into shape, making them much more resistant to detonation and high cylinder pressures compared to cast pistons. This means they can handle more abuse and are less likely to fail under demanding conditions. The 3.552-inch bore size is specific to certain 4.6L configurations, so it's important to confirm this is the correct size for your engine build.

Keep in mind that these pistons are not CARB approved and cannot be shipped to California. Always refer to your engine builder's specifications and the manufacturer's installation instructions for proper fitment and assembly.
