G4NB 1.8L Nu MPI Bare Engine / Long Block – Hyundai & Kia Replacement Engine
This G4NB 1.8L bare engine is a complete long block assembly built to OEM standards for Hyundai and Kia vehicles. Part of the Nu engine family, the 1.8‑litre DOHC unit features D‑CVVT (dual continuously variable valve timing) for a smooth balance of power and efficiency. The assembly gives your vehicle a factory‑fresh start for an engine swap or rebuild, saving you time and money compared to repairing a worn or seized engine.
