Spark Plugs

What is the procedure for removing spark plugs from my 99 LS 400? I had little problem on the left side four. However the right side is covered by what I think is part of the air cleaner housing. How is it removed? jerry j.

to remove the air cleaner house its just takes some time. its easy though, it just has a few 10 mm bolts that hold on the air cleaner housing then, remove that,and loosen the clamp to from the intake pipe and remove there is another clamp on the throttle body, do the same. i think there are a couple of small heat sheilds, that require 10mm socket. and then ur good to go. u'll be able to do it, it just takes time and a little patients
