Not really any justification other than the usual "the car is designed this way and should stay this way,modifying the airflow other than the way its designed will cause issues".Of course me,car ignorant and having never modified a car took him at his word.Ive read one of the threads on how to make your own,pretty cool.Perhaps someone could also tell me of a site that has ones made for our cars.I went in pep boys and they had a few,but none for my car.And cool on the headlight assembly,i wont mess with anything but those two bolts.Im just trying to replace that farthest running bulb anyway.
