    Hood Scoop Grill Insert

    Ive been looking to get a Grill Insert for my hood scoop to reduce the amount of crap that flyes in the scoop.

    and on Subaru WRX Performance Upgrade Parts - Mach V Motorsports, they sell pre-fitted hood scoop grills for 02-03, and 06-07, but not the blob eyes.

    does anyone know of any others companies besides Grill craft (which is who i think makes the ones offered on the site) that sells fitted hood scoop grills.

    i do realize i could by the materials and make one myself, but id prefer to buy one fitted for the clean fit, nice look, etc...

    any info would be appreciated...

    You'll also reduce the amount of air that cools the IC. Do you really want to sacrifice performance for looks?

    i wasnt aware that a simple grill would reduce air flow enough to reduce IC performance.
    but if you really think its a reality, ill think again before acutally doing it.
    kinda glad i havent spent any money on this type of mod yet.

    by your logic, would a front bumper grill reduce air flow on my rad?
    increasing operating temps?

    It would reduce air flow 30%-40%. I have both grillecrafts on the bumper, operating temps have not been high, im sure it may have went up a bit, but the temp gauge still stays in the middle. Air still gets in from other areas to the radiator, the IC only has the one opening, and IMO i want all the air i can get going to it, especially during hot summer days. I deal with the little dents in the fits, get a small flat head screw driver and you can bend them back if you want, also can use compressed air to blow out debris and small stones.

I also got one of those and you can tell from the discoloration on the intercooler that there are now 2 main air flow contact points; at the back as with OEM and in the middle thanks to the insert. There's no mesh as part of the insert, so air flow isn't restricted.
    i wasnt looking for something to evenly spread the air over the IC, but more or less a mesh grill that could reduce the amount of rocks and such from flying in there.

    theres a few threads on here about tilting your IC to help it get better air coverage but it doesnt seem crucial to me.

    The loose ones, i got some out with a vacuum, a few rocks wont hurt nothing. Sure it doesnt look the best, but its a car not a show car. If it was a show car you wouldnt be driving it .

    Do you have a source for that data?

    When I tested the temps to see the effect of having a screen in front of scoop there was about a 10*F warmer difference to IC because of screen and the temps took about 2X longer to go down to as cool as it was going to get.

    What kind of screen are we talking about here?

    I find it exceedingly difficult to believe there is that kind of pressure drop across a coarse filter.

    Its common sence man, that grill is going to fill alot of that hole where the air is going into. How do you figure the effects would be nothing?

    Look in my photobucket site under info... The minimum temp difference was 5*F to 6*F warmer IC but the average was around 10*F warmer IC with screen in. May not sound like much but that's about a 20% to 30% reduction in IC efficiency. Not something I would want on/for my car.

    2007 WRX HoodScoop filter

    Guys,
    I get a lot of bugs on top of the I.C.
    had 2 questions:
    1: is the top of the I.C a filter itself and if it is, how can you clean it?

    2: if it's not a filter, where can I get a filter for it for not letting bugs and small flying things getting inside? and is it necessary to have a filter at all?

    Tweezers and a small pick to clean it out and straiten the fins every once in a while is what I do...

    I know this is an old thread, but I have a question pertaining to this.
    I just purchased a 2013 WRX hatch. I would assume the end result of adding the grills would be the same on my model, yes?

    Thanks, Brandi
