which spark plugs?? second service :)

[Type R magik]

had the 06 ctr for 2 years now and doing the second service soon its on 35k miles now.
i dont think the spark plugs have been changed since factory 4 years ago so probably a good idea to change them lol

i saw that it has some denzo spark plugs in their at the moment, are these the factory fit ones and how much do Honda charge for them? and what are the alternatives? if any or worth it.

is their anything else in particular i should be looking to do in the service besides the usual engine oil change and brakes etc?

Spark plugs are every 72k miles or 6 years.
