This is the NGK part number for the stock iridium plugs for the N20. No matter what, check the gap using shins instead of the crap round thing people seem to love using. If you do it yourself please search in the maintenance section of this forum and find the special socket you will need ($15 on Amazon) and the procedure.

You will probably have to order them from whatever parts place you choose.
