hey bub. What XOC is trying to say is it's impolite to type in all caps.

I don't know of anything other than a free flow air filter...try looking for frontier pickup mods, bout the same engine, but the 4 banger frontier is a bit more popular than the 4 banger xterra.

We just traded up from the 4 banger to the 3.3, man, you don't know what yer missing...not just the power, the dang thing rides a hundred times better on the street, and feels much more like a real truck..definitely trade up when ya can, it's a whole different world.
