MAHLE Motorsport Porsche 356 74mm Piston & Cylinder Kit – Slip-In

MAHLE Motorsport Porsche 356 74mm Piston & Cylinder Kit – Slip-In

MAHLE Motorsport air-cooled cylinder kits are engineered and machined to original equipment tolerances while providing increased performance, durability, and longevity.

This Porsche 356 application features a slip-in cylinder design with a 74mm bore. The cylinders are designed as a larger internal-bore replacement while retaining the original case register, making them suitable for performance engine builds where engine case machining is not required.

MAHLE Motorsport pistons are manufactured from high-strength 2618 alloy and engineered for demanding performance applications. The included performance ring set complements the piston and cylinder combination for a complete upgrade.
