hey guys thanks a lot for the help with the sylvania bulbs..right now im startint to do a performed to my car. i will begin with intake. I saw many forums and says that my car NISSAN MAXIMA 95 GXE has a sensor in the box...and yeah...!! it has it so i saw on internet and all kind of maxima sites that theres a filter with a adapter ring on it to put the intake. My question is what do i have to do with the sensor that is on the up part of the box.

and the other is...whats the diference between the intake that is just the filter and the adapter...and a silver pipe with the filter...i saw theres a custon made pipe and filter..but i dont know if just the filter works the same way that comes with the pipe.
