Wiseco VW KR/PL 81.50 mm Bore 32.64 mm CH -7.36 CC Piston Set

Forged from 2618 aluminum right here in the USA, these Wiseco pistons are built for serious performance in your Volkswagen KR or PL engine. The 81.50 mm bore size and specific compression height of 32.64 mm, combined with a -7.36 cc dish volume, are designed to work with your engine's specific cylinder head and camshaft setup for optimal combustion chamber volume. These aren't just any pistons; they're part of Wiseco's Professional Series, meaning they're packed with features for heavy to severe duty race applications.

You'll find precision ring grooves that help ensure a solid seal, along with anti-detonation grooves and other features aimed at improving ring seal under extreme conditions. Wiseco also applies their ArmorGlide skirt coating, which helps reduce friction for quieter operation and resists seizure, a critical factor when pushing an engine hard. The fully machined crown ensures consistent combustion chamber shape, and forced pin oiling helps keep the wrist pins lubricated under high stress.

This set includes four pistons, ready for your performance build. Keep in mind that these pistons are not CARB approved and cannot be shipped to California. For builders aiming for maximum performance and durability in demanding race applications, these Wiseco pistons are a well-built choice.
