    Radiator Shroud

    I was thinking about buying a Perrin radiator shroud and was wondering if has any performance aspects to it. Through my internet research i have found mixed reviews, some say there is a performance aspect to it, some say it's negligible, some say it's just an engine dress up piece. What to you folks think?

    It makes sense that any more air that you can get through your radiator the better you will be, but I have heard that if you look at the side of the radiator it has gap's that will negate the shroud therefor its just an engine dress up piece.

    Have you seen any measurements of air flow and/or coolant temps before vs. after?

    If not, I'd see no use beyond aesthetics.

    Then see if it's worth the money to you for the looks.

    i have a the grimmspeed cover and love it. that said, ive noticed absolutely no gains from it. my temp is stable at the exact same temp with or without. verified by eyesight, torque app and elm32, and a few gauges. as far as airflow goes on my stocker...*shrug* i was after the tool tray and looks myself.
    when my friends come up, i hear, "you sold the camarrrroooh.....HOLY BLEEP A WRX!"
    Ya has that effect on me too.
