Howdy everyone~

I have purchased a K & N filter charger today for my 2003 Xterra. Becuase no 2003 K & N filter charger were available yet, I had to go for 2002 ones, my questions are as below.

1.My K & N filter charger is actually bigger (fatter) than the the original ones from the factory. When the original factory air filter ones fits perfectly into box easily, my new K & N filter charger would not fit into filter box, so it is like the rubber part of K & N filter charger sandwiched in between the box (Which I was hardly able to clip it back to close it but not fully closed becuase of the fat filter rubber-). Is it common problem for every X or if i have Wrong one put on for my truck?, would it be okay if the filter box was not closed fully but it is sealed like mine as I explained obove?

2.Does anybody know if the 2003 filter box size is differ from 2002. When I checked at the dealer it looked the same althoug I did not actually measured with measuring instrument.

Many thanks in advance for your reply
