I did ABA testing on a WAI for my xB. Net results showed no difference in fuel economy. I keep it hooked up in the Winter, and have grill blocks, because logically they must help warm-up times. Even with both, my xB doesn't reach 59 degree C operating temperature until I'm 4 miles down the road, in 10 degree C ambient temperatures.
