You want 4 prong spark plugs. Ngk and Bosch are the two brands to use, but some people had problems with bosch. I didnt, but you should buy a set of 6 ngk laser platinum oem plugs. (4prong). Make sure they get torqued properly !!!!!!

Also the lean code means you got an intake leak. Check your intake boots first
