if you have a fairly basic engine, in good condition and in a good state of tune, you'll get ten years out of sparkplugs.

and if you get platinum plugs you only replace them every 100,000 kms on a healthy engine.
Regular (quality) servicing gives you improved reliability, which means less breakdowns on the side of the road.

Yes, the plug is fouled. It's not a bad plug, but something is wrong with the engine. It will foul the next plug you fit.

Now your task is to find the cause and repair it.

#4 seems to cop the PCV fallout I've found. . . a little darker but nothing extreme.

Are you having any issues with the float level?
If fuel is pooling, it usually end up in #4 too. . .

be careful removing and replacing spark plug leads while the engine is running.

a good spark will jump a fair distance, and they bite really hard!

NGK BPR5 is a correct plug -- See Spark plugs.
NGK BKR5 is I don't know what it is

It is not causing the problem, or all the BKR5E plugs would be fouled. Unless you are using other plugs in the other three cylinders...
