I changed my original air filter at 15k and put in a fram filter from walmart. I had so much trouble getting the air box to fit back correctly that i swore i would only use a Nissan filter next time. the original one with the black gasket would go back in perfectly but the fram with the orange gasket was a big pain. well, it is next time so i ordered a new OEM filter from courtesy parts. got it today and damned if it doesn't have an orange gasket with white paper. the original one had a black gasket with pinkish paper. it has the correct part number (16546-7S000) printed on it along with "made in mexico." No box, it is in a plastic bag with no markings. So did i get another fram or did Nissan change something, or both?
