Product Description:
The WPR 0.50 Oversize Piston with Pin is engineered for the Toyota 1KZ turbocharged diesel engine, providing a reliable replacement for engines that require a slightly larger piston due to cylinder wear. This piston includes a carbon-reinforced head and upper section up to the second ring to ensure enhanced durability and heat resistance, which is essential for high-compression diesel engines. The piston skirt is coated with MoS₂ (Molybdenum Disulfide) to reduce friction, minimize wear, and promote smoother operation, extending the life of both the piston and cylinder.
This 0.50 mm oversize piston is designed to restore lost compression and performance in high-mileage or worn engines. The package includes 1 piston and 1 wrist pin for an easy and precise fit. With OEM part numbers 13101-67030 and 23218J, this piston meets Toyota’s original specifications, making it a dependable choice for the Toyota 1KZ engine.
