Plugs - R43TS6?

[GNX243]

I've been running R43TS plugs and before getting the car out decided to change the plugs. I see there is a R43TS6... Looked all over to find out what the 6 means to determine the difference between these plugs but can't find that code description. Anybody know and is it better to run this plug?

Thanks for your comments

The 6 means they are pregapped at .060. I would prefer not to run them but you could reset the gap and be OK.

THanks....I thought it might be a new advanced design. I will just stick with the R43TS plugs

Mine said R43TSC I believe. Read that the C stood for commercial. Heavy duty electrode. I think I found that info on gnttype.org
