Finally got to replace the spark plugs in my Pilot. They were original with 90,204 mi, never replaced before. Surprisingly, it wasn't hard at all, even the rear bank. Took me an hour or so. Unplugging the coils was not as hard as I thought it would be - I'd pull the rubber boot up and it would give an easy access to the tab. Below are the pictures of the plugs that came out. Bottom row - front bank, upper row - rear bank. Same exact plugs (bought at RA) came back in.
