Product Description:
The WPR 1.00 Oversize Piston with Pin is precisely engineered for the Toyota 14B diesel engine, providing a robust 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, offering 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 ensure smoother operation, extending the lifespan of both the piston and cylinder.
This 1.00 mm oversize piston is ideal for restoring lost compression and performance in high-mileage or worn engines. The package includes 1 piston and 1 wrist pin for an easy, precise fit. With OEM part number 13101-58040, this piston meets Toyota’s original specifications, making it a reliable choice for the Toyota 14B engine.
