Do I just install these or do I need to gap them to a certain specification?

thanks !

again NGK PFR7G-11S

 

if you bought them from a dealer they should be pre gapped but its always good to just make sure and adjust them i fneed be, but be very carefull not to chip the electrode or damage any of the spark plug.

here ya go !

11S means that it's already pregapped by NGK. No, not really.

 

I rarely come across any supposedly pregapped plugs that are accurately gapped to spec. I always check mine and most times have to readjust the pregapped plugs to spec.
