Airbox Mod
well after doing some reading around on here I opted for just modding my airbox, and getting a K&N Filter, instead of dishing out $300 for a CAI or Icebox.
So anywyas, I took out the resonator - and no you DONT have to remove the front bumper to do this. Took me all of 20 minutes to get it out after getting the wheel well liner out of the way. Threw in the K&N and was good to go. Noticed a definite butt dyno difference. Nothing monumental but seems to rev a bit smoother/quicker and shift at a bit higher mph.. anyhow.. considering the cost I'd say it was well worth it.

I'd really be interested to see what this runs on the dyno...
CT's cold air box dyno numbers are well known, but no one has ever run the numbers on the K&N w/o the resonator vs. the stock setup...
<--- has K&N, just has to get motivated to remove the resonator... Joe from Warwick showed me the trick to get it out w/o removing the bumper...

as a side note mine was full of bugs and leaves.

i have the resonator removed and a piece of aluminum dryer hose fitted to a PVC coupling which is jammed into the airbox. the end of the hose is aimed right out in front of the radiator to get a direct shot of cold air through the bumper opening. it sounds kinda ricerish , but i think it serves great function. plus you cant see any of the piping or any of that anyways cause i have it hidden in the bumper.
IMO its better than the CT box cause your getting air from outside the car and not inside the bumper. ill try and post pics up if anyone wants to see

I'm all over this mod. I was thinking about doing this when I took my Weapon-R off and put the stock air box back on minus the resonator. Great picts, too. I'm curious though if the plastic that normally blocks where the opening is a removalbe plastic plate or is it one piece and you have to cut it out of the plastic insert?

The insert is all one piece, you'd have to cut it out

As far as butt dyno I noticed a difference. I will hopefully be dynoing again next month. The only thing I have changed since my last dyno is the "ice box " and "thermal block spacers". The spacers don't really give any hp it just helps keep the hp you had. So it should be a good test to see if the comptech is better than my setup. I think it should, now if it's going to be a substantial amount is another story. The comptech just has a smoother flow of air.

I took every thing out, and have just a cone filter attached to the IM snout.
Just kidding. I actually have the resonator removed with K&N filterrrrr

anybody have a link to a DIY for the resonator removal without front bumper removal? I did a couple searches and I came up with dead ends. The original website that had the DIY is out of order it seems. Also, has anyone come up with a solution to the humming noise?

check that out and you might find this to be easy to remove the resonator...
or if you have small hands, just remove the tire and fender well and you'll see to bolts...remove those...10mm i think for all three...(12mm usage maybe) the last bolt is a pain because you have to situate yourself so you can get the feel for taking it off...unless...you want to go the other route and remove the bumper.

-Turn the driver's side wheel all the way to the left.
-Under the front right of the car, in front of the wheel, there is one bolt and two of those plugs you need to undo.
-In the wheel well, undo some of those plugs that hold the liner in place, there are 3(maybe 4) that can come out. Pull the liner out from the bumper, it won't come completely out, but it will give you more than enough room to get to the three bolts holdin the resonator.
-One bolt is in the front of the resonator(it runs parallel to the body of the car), you can feel it with your hand under the bumper or you can just put your head under to see it. A 10mm socket will remove all the necessary bolts.
-The bolt on the back of the resonator can be seen from peeking in through the exposed wheel well.
-To get to the top bolt, just feel the top of the resonator and undo it.
-Once all of the bolts are undone, just pull the resonator out. If you want to take the U-tube thing out, just pull it straight down after the resonator is out.
It may seem intimidating, but it is a piece of cake once you are down there. It took me a max of 10 minutes to remove all the plugs and have the resonator out and I am not very mechanically inclined.

so is the general consensus that if you leave the u shaped tubing underneath, the resonance is minimal? and if the resonance is unbearable, is it just the opposite set of directions to reinstall the resonator?

Personal preference for leaving it or not.. I think if your gonna take the the U shape tub out you should probably put a hose to the front of the car or something for cooler air.. Mine soudns fine with the U think still in there. maybe a bit louder at higher RPMS but nothing crazy. And TallyCL-S did the same thing I did to remove it.. I took off my tire though =P

ok i just took out the resonator, but the u-tube thing seems to just hang there. The tube just fits semi-snug into the rubber gasket leading to the airbox. It looks like it'll bang around when going over bumps, so I'm going to keep it up there with some fishing line or something i guess...

update: the fishing line idea doesn't seem to be a good one considering movement would probably eventually cut it, so I don't know what other people did. Just fit it into the rubber gasket as far up as possible and forget about it?
