Wiseco Peugeot EW10J4 85.00 mm Bore 29.60 mm CH -18.00 CC Piston Set

If you're rebuilding the engine in your Peugeot EW10J4 for serious racing or heavy-duty performance, a strong set of pistons is crucial. This Wiseco Professional Series piston set is built from the ground up for demanding applications where reliability and strength are paramount. Each piston is forged from 2618 aluminum, a material known for its improved tensile strength, making it well-suited for the high stresses of performance engines.

Wiseco machines these pistons right here in the USA, paying close attention to details like precision ring grooves, anti-detonation grooves, and features that improve ring seal. This attention to detail helps ensure consistent performance and durability under severe operating conditions. The pistons also come with a special ArmorGlide skirt coating. This coating is designed to reduce friction, resist seizing, and contribute to quieter operation, all while handling the intense heat and pressure of racing.

This set includes four pistons, each with a 85.00 mm bore and a 29.60 mm compression height. The crown of each piston is fully machined, and they feature forced pin oiling to keep the wrist pins properly lubricated. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For a robust engine build that can handle severe duty, this Wiseco set is a solid choice.
