Some other people might disagree, but unless you're made out of money, I'm from the "don't fix what ain't broken" school. You might want to have sensors on hand in case one of them strips the threads or won't come out clean, but buy them from someplace that allows returns. If you go aftermarket, make it Denso. They make most of Nissan's HO2S's and generally won't screw anything up. You're taking your chances with Bosch, NTK, Hitachi, or China-cheap stuff, they don't always work right. China-cheap is a bad idea for the cat as well. My customers have had good results with Bosal, AP/Eastern, and the higher-end Walkers. If you go bargain basement you're asking for trouble, I've seen many people end up with sensor spacers and in one instance a China cat that failed before 10K and took out the whole engine. 'Nuff said.
