Alot of people remove the palstic tube and just leave it alone because the filter is right there. There are many claims of added horsepower and improved gas mileage with this modification. You may also want to look at picking up a K&N air filter for you fusion also because there is suppose to be less air restriction and impreoved preformance. Check out some of the other post that say airbox resonator modification. Hope this helps.
do you mean the bent tube that goes nowhere after the airbox but before the intake?
or do you actually mean the tube coming out of the airbox itself, that looks like a horn,
that goes into the fenderwell?
Both, when you pull the tube that goes into the fenderwell the one that just underneath that goes into the box is attached, so effectively they both come out. You will see when you take the one in the fenderwell off. There is a post on here with pictures.
I was referring to what tube he actually meant, I already did the air horn removal, a long time ago.
there are two tubes, one that is right of the airbox (the air horn), and one that is between the
airbox and the intake, that shoots back towards the airbox on the V6, on the I4 it is just a little half
Cross Bolt is right, it's really called a Helholtz Resonator, there are two on the intake tract. One in the front left bumper which everyone has been removing to increase the air flow, and this one. Since there is no actual exposure to air it's just meant to control the intake pulse for sound control. However, you may want to investigate a little more before removing it, doing so may cause issues with the MAF sensor and cause idle quality problems due to the different harmonics coming from the throttle body. I ran into these same type of issues when I made my own cold air intake for my I4. There is no performance gain from removing it, but it sure is ugly. :cheers:
I really didn't see anyway that it would affect anything, so I never messed with mine.
however the one on the 4 is a lot smaller and really isn't bothersome. but the one going
into the fenderwell, off the right side of the airbox, is the one most people are removing.
