Hey guys like most people was looking to get better MPG.
First of all i average 27 mpg and i did the grill block to both grills, I started with the bottom and got 27.5 -28 and had no overheating issues.
I had time this weekend to do the top one and drove around; Here in so cal this week the temperature outside was about 105 so i had the AC on when i noticed my car temp sky rocket.
I need to modify this full grill block to be a partial but dont know which grill to modify. and how much?
Heres both(well bottom out)
and some close ups
