I installed my new aerosync front bumper not to long ago. And I wonder if a grille is necessary?

And also there are black plastic shield looking things on each side of the opening now noticeable. Are these things there to protect something? I bought the grille material but would have to take the bumper off again to install it. Its kinda to hot outside and my body is saying Hell no

 

u can take them off..a lot of members have done that...no problems.

 

well let say this.. I didn't put my grill on my Ing's N Spec front and a rock hit my A/C Condenser while driving on the freeway and I end up having to pay for a new condenser.. so i will never have a bumper with your the Grill (screen)
