How to Access Spark Plugs on a Onan Marguis Gold 5500 Gas

I have a Onan_Marguis_Gold_5500_Gas Generator (5.5HGJAB-901B Spec B) Looks like it has 2 plugs - One front right and one rear left according to manual as looking through the panel.
What is the best way to access the spark plugs in order to replace them?
The one is the rear I can't even see from the side panel.

Thanks for any help.
  • Just replaced the plugs in mine. Pretty easy to do. Remove the air filter housing and you will see the plug wire. Plug is in the identical position of the one on the right, not really in the back of the genset.
