CP Piston for Ford 4.6L - Bore (3.572) - Compression Ratio (8.4:1) - Set of 8

This is a set of eight forged pistons from CP Pistons, specifically made for the 2003-2004 Ford Mustang with the 4.6L engine. These pistons are designed to achieve a compression ratio of 8.4:1 and have a bore size of 3.572 inches. Forged pistons are a strong choice when rebuilding or upgrading an engine, offering better durability and performance potential compared to cast pistons, especially under higher stress.

CP Pistons are known for their well-built components, and this set is no exception. The 8.4:1 compression ratio is a notable figure, often chosen for naturally aspirated builds or those planning forced induction where a slightly lower compression can help prevent detonation. The 3.572-inch bore is the standard size for the 4.6L Mustang engine, meaning these are direct replacements for your stock pistons, simplifying the installation process for your engine rebuild.

When installing these pistons, ensure you follow the manufacturer's recommended clearances and lubrication procedures. Remember that this part is not CARB approved and cannot be shipped to California.
