```
import boto3

# Initialize a Boto3 EC2 client
ec2_client = boto3.client('ec2')

def fetch_instance_metrics(instance_id):
    """
    Fetch CPU utilization metrics for a specific EC2 instance.
    :param instance_id: str
    :return: float
    """
    cloudwatch_client = boto3.client('cloudwatch')
    response = cloudwatch_client.get_metric_statistics(
        Namespace='AWS/EC2',
        MetricName='CPUUtilization',
        Dimensions=[
            {
                'Name': 'InstanceId',
                'Value': instance_id
            },
        ],
        StartTime=datetime.utcnow() - timedelta(minutes=10),
        EndTime=datetime.utcnow(),
        Period=300,
        Statistics=['Average']
    )
    return response['Datapoints'][0]['Average'] if response['Datapoints'] else 0

def scale_instance(instance_id, target_capacity):
    """
    Adjust the instance capacity based on current utilization.
    :param instance_id: str
    :param target_capacity: str
    """
    ec2_client.modify_instance_attribute(InstanceId=instance_id, Attribute='instanceType', Value=target_capacity)

def main():
    instance_id = 'your-instance-id'
    current_utilization = fetch_instance_metrics(instance_id)
    print(f"Current CPU Utilization: {current_utilization}%")

    # Define utilization thresholds
    if current_utilization < 10:
        scale_instance(instance_id, 't3.micro')
        print("Instance scaled down to t3.micro due to low utilization.")
    elif current_utilization > 80:
        scale_instance(instance_id, 't3.2xlarge')
        print("Instance scaled up to t3.2xlarge due to high utilization.")

if __name__ == '__main__':
    main()
```

This Python script uses the AWS Boto3 library to interact with AWS EC2 and CloudWatch services.
