Grill blocks help mpg intwo ways; better aerodynamics and quicker warm-up times. If you pulse and glide with the engine off, you can keep engine heat in with a blocked grill. IMHO an adjustable grill block behind the hexagons would benefit you much more than a slightly more aerodynamic but fixed grill block in front of the grill.
