spark plugs on Lexus IS200

My IS has over 170.000 km driven. As I have become a happy owner of this great car when it was 150.000km "old", I don't have a clue whether the spark plug have been replaced or not. Also I wasn't sure about the condition.
This is not any how-to, but at least you cas see how to access them.

First you must remove both parts of airbox. the each hold 3 screws.
Start with the front one:

then remove those 3 screws and pull out the main part of airbox. Prior to this, I removed the air filter. There is it is:

Next step is pretty straight forward, as you can see on following images.

remove the cable, unscrew and pull out:

as you can see, there is NGK IFR6A-11 which is one of the two recommended spark plugs (iridium only).

  1. I am not sure, but i think one my spark plugs might not be firing. My Lexus was driving smoothly 2 days ago and now suddenly it is vibrating, doesn't idle as smoothly as before and lack of power. also strong smell of fuel while driving. Car starts fine. So i am thinking it might be the plugs as i have never ever changed them.
