I have not seen any gains either, on my 5th tank of gas with these plugs, no fitment issue on my civic.
I've tried other plugs as well, like the Bosch +4 and I did have trouble with my civic not running as smooth with those plugs.
I plan to switch back to NGK copper core v-power plugs that are recommended by Honda next time I change plugs, I've always had good luck with them.
