CAI idea will it make a difference?

    Brainstorming!!!
    I have a fender mounted cai. I was thinking of putting the oem air duct intake back on (after modifying it a bit to fit around the aftermarket maf tube) to cover the big opening and possibly force "cooler" air, instead of the current heat going in from the engine bay. Will it make a big difference?

    EDIT: Here's a crappy BB pic I took after modifying and installing it

    theoretically yes

    realistically enough to feel a difference, probably not

    but worth a shot, sure

    You will probably benefit more from cutting the duct to blow outside air directly onto the MAF itself. If it heat soaks the ECU will adjust.

    Using the stock snorkel to direct "hood-height" cool air at the filter is a very good idea.

    Yeah as long as the air flow from the snorkel isn't pushing into the filter in the direction of the intake itself! Remember the ram air issue that we never could figure out until WJM looked at the car? :rofl:

    Thats what it's doing now after having to cut the duct to fit. Makes sense!!!!

    Stock air box intake system on the wrx and pre 08sti is the best system out there up to 360whp.

    There won't be.....save your time. You are just keeping the intake temps cool.

    One the dyno you will see no difference.. what you should do is monitor you air intake temps before and after the mods and see if they change.

    Ok. Had my AP monitor it for a week (with and w/o the ram air duct) seems to be a ~10 degree difference with it installed. Not sure if it's a significant number but hey it's a little cooler and it was free.

    ~10 degrees cooler for something you didn't pay for? I would say that's fairly significant.

    I still have stock air box on mine. Had CAI before, but i bought a stock airbox on here. Didn't feel any loss from deleting the CAI. And I don't have to worry about CAI sucking water into my motor again.

    It should be okay if you had the splash guard on, shouldn't?
    My CAI is fine, although my car is at stock height with the splash guard. I've driven through some really heavy rain, but I've never hydrolocked.
