Third tank was 31.9 MPG. Maybe it's the cold snap, but it sure hurts my efficiency ego. My car originally came with a front license plate bracket that I removed because A: I think it looked ugly, and B: it isn't required in Georgia. For the grill block, I was thinking of making something out of black plastic roughly the size of a license plate or slightly larger and mounting that to the grill via the bolt holes used to hold the front license plate bracket on. It would be somewhat recessed within the front bumper. Would this have a desirable impact on drag by partially blocking air entering the engine bay, or would this create more drag?
