In theory this would somewhat work in combo with a less restrictive drop in K&N filter. But the Volants intake tube going from the box to the throttle body is smoother and larger than stock, 2.5"dia. ram air port in the box, the hole in the side of the box is the same size as the hole in the fender with a rubber seal (this hole is approx 3"x4"), and it has a much more efficient conical filter vs. a drop in with less surface area. On a budget for a $40 drop in and cut down the fender port would be a slight improvement and be alot better than a K&N FIPK or similar non cold air cold air intakes but wouldnt be near as efficient as the Volant.NVSteve wrote:Here's some food for thought, and by all means post your thoughts on the matter. One of the Xterra forums has a thread talking about the stock air filter & housing. In short, if you remove the filter housing lid/cover & the air filter, you'll see a plastic pipe jutting out into the housing. A number of Xterra owners have cut that pipe flush with the walls of the housing. The theory behind it is that the air was only penetrating/flowing through one tiny little spot on the air filter (lots of pictures prove this) in the stock setup. People have mentioned that it does make a nice sound & a few have mentioned a bit more pep on the throttle. The air intake we have is essentially a sealed CAI to begin with, but this mod seems to improve upon it. I have it on my list of things to try, but if anyone else wants to give it a go, by all means post your findings here.
The tubes inside the resonator are purely for sound control. Removing them won't change airflow characteristics in any significant way. Induction noise has trouble propagating around hard turns, so they design a labyrinth inside the airbox to reduce it just like some muffler designs on the other end.NVSteve wrote:Here's some food for thought, and by all means post your thoughts on the matter.
