There are mixed opinions on whether to replace all ignition coils at once. Some mechanics recommend replacing the entire set to prevent future failures, especially if the vehicle has high mileage. Others suggest changing only the faulty coil to save costs. Many Hilux owners find that when one coil fails, others tend to follow soon, making a full replacement a wise choice in certain cases.
