    Wait, are you referring to the splitters on the front?

    I'm sure you could modify it to fit also, but you asked if it would work, not if it would need to be modified to fit. For your application you might need m4D-tyt3 JDM parts.

    Are you running a STI intercooler?? What IC are you running?? You get the splitter/bellows that works with the IC you are currently running.

    I think we should make a hood scoop patterned after the air intakes on F1 cars. It could be a foot tall and wide enough to suck in readymix...

    AFAIK the STi splitters pre 06 require an STi size hood scoop or you need to do some modding.

    Someone posted on nasioc (sorry I don't have a link) recently that upgrading (enlarging) the scoop does almost nothing for you're intercooler at highway speeds, something about the air coming through the grill and radiator has so much more pressure than the air trying to come through the scoop, that air actually ends up coming up through the engine bay, and out the scoop.

    Don't know if it's true, but he seemed like he knew what he was talking about.
    Just thought I'd throw that out there.

    When asked what solution he recommends, the recommendation was "stick with the stocker".

    I did hear that a bigger scoop does not do much. However i will need a splitter to make sti top mount fit well.

    That is kinda BS. At highway speeds, yes. The key to the whole thing is the cool down time. I have been running temp probes in my ic since I have had my car (7 years now). the STI scoop makes a difference on cool down time. The part about the air coming out of the scoop is bs. Most of the air that comes in the grill area goes out under the car, not around behind the motor and up through the IC and then out the scoop. Not going to happen, and I have tested it with strings that i taped to the top of the scoop. From all of my testing, the STI scoop and some kinda of splitter (not the bellows) makes the IC cool of quicker (less time/mileage) than the stock setup. As for air temps, the once you are up and moving, your IC gets down to right about ambient temps. The biggest factor that I have found with post IC air temps is the intake. Short rams pretty much add 20-30 degrees to the post IC air temps and the stock box/cai keeps them right around ambient temps.

    So Taras, you need the splitter for the IC. So if you are using a USDM STI IC, you need the USDM STI bellows, if you are using a JDM IC, you need the JDM bellows. The idea is to have the hole in the bellows match the IC and to have the hood sealed to the IC to promote quicker cooling.

    04 sti scoop, drill, cut off wheel, doublestick tape and some sort flavor of sexy bikinni girl to sit in the background telling you how well you are doing.

    imo, just put the ic in and call it a day.
    honestly, you're gona run out of IC capacity before you run out of hood scoop air flow...

    Well if i put sti top mount and stock splitter i dont think the hood will even close and if i dont all the air with watter will just get sprayed all over the place.

    should close just fine. You can always cut the back corners of the bellows (nearest firewall) for a temporary fit. front corners too if it's even necessary.

    The stock splitter and bellows have a smaller opening compared to the sti intercooler. so if anything, you will have a fairly tight seal but won't be maximizing the useable surface area of the sti tmic.

    As for water spraying through the intercooler and getting all over the engine bay... it already goes through. PLus you probably get plenty coming up from underneath. Either way, it won't be any worse than it already is unless you run no bellows.
