Plug in your specific production month/year and find out which plug you need. M52's are picky about which plugs they like, and you should stick to OEM in this case.

NGK BKR6EIX, I bought my last set at Kragen for $5.99 Never mind, that plug doesn't seem to work for the 318. I don't see an Iridium listed for your application.

they are Bosch, and apparently denso ik20's will work. I will compare them before I try and put the new ones in though.
