Google shows that they're the one with projected centre electrode- those are some hot, hot plugs. Why'd you want to use them, that too in heat range 5?
If you're planning to install them in 99 City, I'm afraid they're the wrong ones, as most Honda motors use heat range 6 plugs.
If it's another car, an old craby Suzuki for instance, you'd be fine with a step hotter plug, as long as you're not running on CNG.
Just get any old NGK plugs with 1.1mm gap (11) and 5 or 6 heat range, according to your engine's demand.
