Unfortunately, you missed the part about the rear bank of plugs. The Murano engine is transverse mounted, meaning the V of the engine is sideways when looking from the front.

In order to change the spark plugs in the Murano you need to remove the intake manifold as well. This includes disconnecting the throttle body and probably draining some coolant as well (most cars circulate engine coolant through the throttle body). Each of these bits require various gaskets.

This is one of those jobs that while you have it open, you may as well check everything else. Verify you have no oil leaks around your valve cover on the backside (common) and verify all your vacuum hoses show no signs of cracking.

Good luck!
