1UZ EGR Block Plate - Back of Cylinder Head invetory White smoke from the exhaustThis 1UZ EGR Block Plate is designed to replace the crack prone EGR pipe connecting the back of the 1UZ cylinder head to the exhaust manifold. By blocking off the EGR port, it allows for reliable testing of the EGR function or off road use. Crafted for durability and precision fit, this plate provides a straightforward solution to common EGR pipe failures in 1UZ engines. Note: intended for testing or off road applications only.
