Today I was bored so I decided to cut some of the plastic that is on the back side of the headlight where there are 2 screws to install the cover. I used my air compressor to blow air before and after and felt alot more airflow after trimming away some plastic. I doubt it will actually help much but it even if it helps a little it didn't take much time. I forgot to take a before pic so I took a pic of the drivers side just for comparison.

 

Good idea! Let us know if there's any difference. I have this cover also.

 

man...you really were bored...lol I say every little bit helps..until the lights are up.
