If this is for your Nissan then one small detail may be of note.. your air filter may be very lightly oiled. The OEM ones may very well be lightly oiled. If this is the case then I know that the higher end STP air filter is as well. I have the Purolator higher one end now and it was lightly oiled when I first put it in. I would think the Fram TG ones are too.?
I've used the stp ones which were just fine.
