it is killing your mileage because your stepping on it more to hear the intake [hihi]I have the cover off right now. I love the way it sounds, but I think it's killing the mileage and it's not able to get the amount of air it gets with the cover on. After work project I suppose. How much does the filter cost?
Any idea on the difference between the two oil filters?
You probably don't want to do that. Those tubes are sucking air from the front of the car- it ends in the open slot of the grill, this pulls in cooler air from the outside for better performance. It doesn't feed directly into the resonator as that is a separate box on the bottom of the airbox. The tube is spit to allow even airflow distribution along the top and bottom of the filter; again, getting rid of it would hurt performance. Just taking the resonator off seemed to help with power, as the hole is in the bottom of the air-box and is fairly isolated from the rest of the engine I think its pulling in relatively cool air. My average mpg (miles traveled/gallons purchased at next fill up) also went up from 27.5 to 31 driving back and forth to classes.DVolpe's picture of the K&n also shows the are intake tube on the left.
One can see the restriction in that tube, where the tubing from the front, splits in two, half for some sort of resonator control, and the other, with a restriction in it, to the box.
If someone made a rubber part which took out the resonator control bit, and just had a straight in to the box, it would double the area opening to the box.
And i(hope) it would sound good.
This is the one thing I want to do to the intake besides the K&N.
