Wiseco Opel Vauxhall X16XE 4vp -15cc 79.5mm Bore 11.5:1 CR (Built on Demand)

If you're rebuilding the engine in your Opel Vauxhall X16XE and pushing its performance limits, a set of Wiseco Professional Series forged pistons is a solid choice. These pistons are built from the ground up for serious racers and builders who demand durability and performance under heavy or severe duty conditions. They are designed to handle the stresses of high-performance builds, giving you the confidence to push your engine further.

Wiseco crafts these pistons in the USA from 2618 aluminum, a material chosen for its improved tensile strength, which is crucial for pistons that endure significant heat and pressure. The machining process is meticulous, featuring precision ring grooves, anti-detonation grooves, and other features aimed at improving ring seal and overall combustion efficiency. The crown is fully machined for a clean, consistent surface. Additionally, the ArmorGlide skirt coating helps reduce friction and noise while resisting seizure, contributing to a quieter and more durable engine operation. The forced pin oiling design ensures the piston pin stays well-lubricated, even under extreme operating conditions.

This set includes four pistons, each with a 79.5mm bore and a 11.5:1 compression ratio, designed specifically for the X16XE engine. Please 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 procedures.
