Hello, I took my louver off this winter to have it painted but I sort of fell in love with the way the car looks without it installed. I have heard that the Louver creates somewhat of a vacuum which cools the engine better. Is it really that big of a deal? I never drive my car when it rains so I am not worried about water entering the engine compartment. Any input would be appreciated. Thanks for your time Peace Dave 6286 [Non-text portions of this message have been removed]
