Referring to the plastic air dam?
Removing the plastic air dam may cause hood lift, like you said. It also may reduce the cooling capacity of your raditor, as removing it will raise the air pressure under the hood. Less air will flow through the radiator. This is not a factor, unless you're under enough of a load (towing, for example) to be on the edge of the radiator's ability to provide cooling.
Lots of people have removed theirs without noticing any ill effects.
I took mine off and installed the MOPAR front skid plate. As far as air flow is concerned, it performs like the plastic air dam. It also protects underneath the front of the vehicle, unlike the plastic one.
