how do you change the spark plugs in a 2005 nissan altima 2.5s?
May have to remove intake manifold to access rear three spark plugs.
There is no "rear 3" it's a four cylinder. Remove the plastic engine cover. I believe you will have to remove the coils, but the whole job is pretty easy. You need a spark plug socket, 12" extension, ratchet, and some thread anti-seize. DON'T GAP THE PLATINUM PLUGS. Put anti-seize on the threads, and tighten until you feel the crush rings give and the plug tightens.
Yep go with the second guy. It's a 4 banger.
