Want to change the plugs but from what I see, the entire air-cleaner case has to be removed in order to do so since it sits at the top of the engine. Has anyone done this before and if so what advice can you give me? Thanks in advance.

It can be done, you have to remove the entire assembly on top, which includes the air breather and the throttle body. Mind you, the spark plugs used in these engines are laser platinum plugs that don't require regular changing recommended changing period is about 30K. Also once you remove your harness to the throttle body you need to do a reset for the idle air control valve and the throttle position sensor. I did it once, end up bursting the rubber air intake seal. but replaced it and no worries.
If you want I can upload the manual for anyone requiring it.

Thanks for the response turboconch2. Where did you get the seals to buy? Since some of the seals and gaskets may definitely need replacement, are these also available? I will try my best to gently use an even force especially above the intake manifold joint but you know Murphy's law is always there.
I want to use some Denso Iridium plugs (IKH16) on it later when I get them from Amazon. I am a bit worried about the Throttle valve closed position learning and the Idle Air volume learning. Is it possible to take off air cleaner case without disconnecting the harness to the actuator to avoid this?

I ended bringing in from amayama.com the seal because N&M didn't have any, actually they said they've never brought it in the country, so i probably just screwed up
The resetting is not difficult as you so have to remove the harness for ease of access. the idle air reset is a little tricky but i got it on the second try. everything is on the manual, i keep forgetting to load it by the way, sorry. look out for it later
