Wiseco Ford DOHC V8 4.6L 4 Val NA/Boost/Nitrous Top Ring Down .300in -20.0cc 3.572 Bore 8.2:1 CR

Forged from 2618 aluminum, these Wiseco pistons are built for serious performance in your Ford 4.6L DOHC V8 engine. This material choice gives them improved tensile strength, which is crucial when you're pushing your engine hard, whether that's with a naturally aspirated setup, turbocharging, or nitrous. The -20.0cc dish volume and 3.572-inch bore size are specific to certain engine builds, aiming for an 8.2:1 compression ratio when paired with the right components.

Wiseco didn't stop at just the material. These Professional Series pistons feature precision-machined ring grooves, an anti-detonation groove, and other features designed to improve ring seal. This means better combustion efficiency and less blow-by, which is essential for durability under heavy or severe duty conditions. They also come with an ArmorGlide skirt coating, which helps reduce friction and resist seizure, contributing to quieter operation and longer life.

The crown of each piston is fully machined, and they incorporate forced pin oiling to ensure the wrist pins stay well-lubricated. This set is designed for builders who are serious about performance and durability, with features that stand up to demanding race applications. Keep in mind 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.
