there isnt a write up for this, as far as i know, so i snapped some pictures while i was taking mine apart.
there is no real benefit from doing this, other than maybe letting out a little engine heat while idling. i just couldnt justify having it plugged for no reason.
this will make your engine bay dirtier, but a clean engine bay is impossible in the desert anyways, and i dont offroad my xrunner hahaa.
I take no responsibility in any way if you mess up your hood or scoop or any other part of your vehicle. as far as i know, this mod is non-reversible and requires a new scoop insert if you dont like it.
this mod literally took only 10 minutes. it took me longer to find some hardware then it took to remove and re-install
pop the hood and remove the 5 -10mm nuts on the scoop
then remove the 1 hidden phillips head in the hole where i am pointing
once the scoop is removed, drill out the 3 plastic rivits. 2 on the top, one on the bottom. when they are drilled out, the plastic plug and mesh can be pulled out.
i didnt want to leave the scoop completely opened, so i found some small hardware and re-installed the screen as seen below
now just reverse the above steps to re-install and enjoy your finished product.
(i placed a flashlight in the engine bay to show the opening)
