After replacing the air filter, (first time, the dealer had done it the past few times)I noticed a gap all the way around. The top cover doesn't close tight against the bottom piece. Used a puraltor filter. Yes I used the right model.

Suppose to be a gap,1/16 of inch maybe, when the clips are locked. Doesn't seem right.

2003 Xterra. Maybe at our next meeting, I can check out someone's X.

Thanks for the info.
