I know some of you folks are still enjoying 70 and 80 degree weather but some of us are in the 30s and 40s already. This is the first winter with the dmax and I'm already noticing it taking longer to warn up. Is there any GOOD aftermarket product out there to block the grill? I could remove the fan, im sure that would help some but...new stuff for the truck is more fun. So what are you guys using? Thanks for the help!
