The WPR 0.50 Oversize Piston with Pin is designed for Toyota 13B diesel engines that require a slightly larger piston due to cylinder wear or for an engine rebuild. Manufactured by CS Factory in Taiwan, this piston is built with a carbon-reinforced head and upper section up to the second ring to provide high durability and exceptional heat resistance, essential for diesel applications. Additionally, the piston skirt is coated with MoS₂ (Molybdenum Disulfide), which reduces friction, minimizes wear, and ensures smoother operation, prolonging the life of the piston and cylinder.
This 0.50 mm oversize piston is perfect for restoring compression and performance in high-mileage or worn engines. The package includes 1 piston and 1 wrist pin to ensure an easy and precise fit. With OEM part numbers 13101-58020 and 23156, this piston meets Toyota’s original specifications, making it a dependable choice for 13B diesel engines.
