Has anyone removed the resonator inside the front bumper cover that restricts air flow into the intake?? I did it on my Taurus and it made a minimal, but noticable improvement in air flow. The mfr does this to quiet the flow of air so there is no "sucking" sound, but who cares about that!!

I have not seen it myself, but my Ford parts computer show maybe a 8" X 10" box inside the drivers side bumper/fender area>

I took out the tube, the air silencer. Made a difference. Easy and free mod. Nice sound, as well.

I have just done that too, removed the tube, which by the way was only about an inch or so from the inner fenderwell
and made for some really horrible restrictions, I removed and now damn, I feel so much more responce, it's funny that
a little bit like that can help so much. The car even shifts so much smoother now, it has made a huge difference in power
and gas mileage, I have done air box mods before but to no end like this one turned out.

ok. So im looking at the airbox. And to the right you have the tube that runs into the fender. But comming off the bottom of that tube you have a small tube going down into another black box about the size of the air filter box. And if you take off the tube that your talking about then that also means you have to take the tube to the other box out as well... Now my main question is what is that other box and is taking its tube out going to affect anything in a negative way?

[/quote]FOrgive me as I removed mine quite some time ago...I don't remember everything.

I took mine off and made sure that everything was pre-air filter, as in I won't be sucking un-filtered air. I am not quite sure what the 'other' box is that you are referring to, but I know I have one too. My thoughts is that if it was gaining and receiving air from the tube and I take the tube off, nothing is changed. It's still getting air from the location that the tube previously occoupied, right? If anything, it's just getting more air and the computer will figure out what to do with it, lol.

For real, I've had mine off about a month now and I've had absolutely ZERO problems. I've been in rain, sunshine and on the beach with sand flying around. I just took my filter out awhile back to look in the bottom of the box to make sure there wasn't no sand build-up, or some leaves or something in there...I was good to go!

I just did mine about an hour ago. There's two tubes. There's a horn that goes directly into the airbox and that meets with a T to another tube that goes to a box. All you need to remove is the horn. The lower box isn't connected to anything after that. You don't need any tools. I had mine out in <2min. Wow, this sounds 100% better now!

Just removed the plastic pipe myself. Very easy mod and creates a path for consistently free flowing air. Did a quick drive, but didn't notice a HUGE difference, but I didn't really give it a good test. I will be interested to see if it does anything for gas mileage

I have about a 300-mile business trip tomorrow. I'll take the tube out tonight and see if it increases the mileage.

Could potentially be different, or something since you have the 4-banger. I think we are all 6's that did this so far. Heck, do it anyway! It can't hurt.

look at your airbox, to the right of it there is a tube sticking out that shoots out into the inner fenderwell
it is held on by two little tabs, remove it, move that little rubber shield out of your way so you can see.
use a flat screwdriver to pry the tabs out and pull the tube towards the fender while doing so. then just take it out of the car

and by the way I do have the 4 Cyl, and did this. and it helped a lot.

(2.3L anyway......)
It does make a big impact on gas mileage, the "miles to E" is dead on within a mile or two
whereas it never was before, and the car shifts so much smoother now, apparently the
air restriction was affecting not only the engines performance. and not to mention I
did see a big diference in the overall performance, it does move faster. my next step
a K&N filter to add to it.

Mine is also an I-4, made a nice difference, very little for mileage though. I have been at a consistent 27 city/highway combined in the cold WI winter!

Here is my results: Trip from Central Ohio to Louisville, Ky.

Trip included about 45 miles back roads(60-62mph with stops now and then) - 72 to 80 mph I-71 and a traffic jam in Cincinnati(30 min) on the way back.

MPG PER COMPUTER***33.4***
ACTUAL MPG CALCULATED FROM FILL UP***33.7*** AND IT FEELS STRONGER

UNBELIVEABLE!!! I DON'T EVEN BELIEVE IT.

My best before was a trip to Indy cruise set on 65mph - 31.8mpg

For those not familiar with the two routes, the road to Indy is mostly flat and the road to Louisville is all up/down hills. I always get better mileage to Indy.

Conclusion: PULL THAT TUBE OUT OF THERE!!! Now get me a K&N cold air kit and let see what that does.

I dont know how you guys are seeing mileage increases. I havent seen any. I dont think, maybe I like the sound a little too much and I am keeping my foot in it. Who knows. I do mostly city [sigh] driving anyway. I need to take a trip on the e-way to prove it myself, lol.

Slight chance milage increases are due to engine break in?

Also, milage from one fill up to another can vary vastly based on the number of red lights you catch (how lucky) you are, and any additional stops you might be making for lunch or shopping.

With my previoius car I would notice milage variations from 29 - 36mpg usually between 32-34.

A more scientific test would be to take the car onto the open road, same road, same day, using the trip computer over 2-5 miles, at a constant speed with, and without the air box attached.

Anyone up for something so involved, time consuming and scientific! ??


All I can offer is the ego trip, and fame of being the ONE person to post REAL results! :)
