I was in the same boat - Honda Prices are too ridiculous.
I bought aftermarket pads - Akebono AN376WK
Parts Central Price is around 6K and they are ceramic, braking is just as good if not better, noiseless and ABS kicks in perfectly.
For the plugs, i bought them from Nomi01 Pakwheels user, he has a sales thread somewhere il try to find it. They were 7200 For all four, this was six months ago and prices may vary.
I still think Honda Genuine plugs can go beyond 100K as the mfg recommends 100K Miles which is 160K
Just clean them using a buffer (dont use wire brush) and emery paper 800-1000grit.
Here’s mine after cleaning.
