The plug change was as easy as an oil change. I used anti-sieze compound on the threads as per instructions in the Honda Service Manual. The procedure took me about one half hour. Won't go into details as there is plenty of how-to information in other threads and also information on torque wrenches. Other than lack of tools, don't see why most of us couldn't change out their plugs. Just my $0.02.

 

i let my dealer do it, so its on record.

 

My dealer registered the change out as if it were performed at the dealership. My only obligation is to return the old plugs as Honda requires this.
