Product Description:
The WPR 1.00 Oversize Piston with Pin is specifically crafted for the Toyota 1KZ turbocharged diesel engine, offering an ideal replacement for engines that need a larger piston due to cylinder wear. This piston features a carbon-reinforced head and upper section up to the second ring, providing excellent durability and heat resistance, 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 lifespan of both the piston and cylinder.

This 1.00 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, accurate fit. With OEM part numbers 13101-67030 and 23218J, this piston meets Toyota’s original specifications, making it a reliable replacement part for the Toyota 1KZ engine.
