Spark Plugs: Normal condition or Dry fouling?

[AlexKJ]

Hi buddys

Please help me on this one... I´ve recently change spark plugs (thank you Blake for your How-To)

This is one of the old plugs... These were the factory spark plugs, and my KJ has now 51.800km (32.300mi).

I've looking this Web page and I can't really tell if it's a "Normal Condition" or "Dry Fouling" case?

Could you please?

Thanks in advance

Looks like pretty normal wear to me,and I can tell you that there plug is gapped close to 2X the specified gap for a KJ,stupid NGK plugs,I'd rather run Champion plugs and I wouldn't put a Champion plug in a engine I was trying to blow up.

Yeah, the plug doesn't look bad, just worn out. I've had good results with NGKs in other vehicles, but haven't specifically used them in a Libby. Ours had nearly-new Bosch Platinums when we bought it (not what I would have used, but they seem to work fine).

It looks ok, a little black, but I wouldn't worry about it. Troy and Belvedere are right about the gap. Looks like you could slide a 2x4 in there. I took my OEM plugs out at right around 30,000 miles and changed them. The gaps on mine were way too wide (worn) also. I was thinking of pulling one after about 20,000 more miles just to see what it looks like.
