you can buy the plugs at your local nissan dealer. Here is the part number: 14052-21R00. Just tell nissan you need that and tell them you can buy them for 8 from a member on here (bernie) and they will beat it, mine did. I would call and order them today because im sure they will have to ship them in as mine did. Good luck and its not that hard at all plus you can clean your motor bay up some if you delete the solenoids.
