Do you see that rectangular black plasitc piece right on top of the engine, Can't miss is, that says Mitsubishi on it? Their all under that. Use the iridium plugs that last for 2 years because you won't want to do this job for a long time after you see what poor design it was and the hassle to do it. 4 hrs. is my estimate if you've never done it before.
