Wiseco Toyota 4AG 4V Domed +5.9cc 3228XC Piston Shelf Stock

Wiseco is well-known for making strong, reliable internal engine components for performance applications. This Professional Series piston is built for your 1985-1989 Toyota MR2, specifically designed for the 4AG engine. It's a domed piston with a +5.9cc volume, intended for builders who are pushing their engines hard and need parts that can handle the stress.

This piston is forged and machined in the USA from 2618 aluminum, which gives it improved tensile strength over cast aluminum. It features precision ring grooves, an anti-detonation groove, and other features to help seal the rings better. The piston also has an ArmorGlide skirt coating that helps reduce friction, resist seizure, and operate more quietly. These are designed for heavy to severe duty performance builds, meaning they are made to withstand significant stress and heat.

This piston has a 82.00 mm bore and a 1.2075 inch compression height. It also features forced pin oiling to ensure the wrist pin stays well-lubricated during operation. Please note that this part is not CARB approved and cannot be shipped to California.
