those are not the recommended one on Wes's site..

Although when I went to the dealer, they said there is 3 different model # of NGK spark plugs.. depending on heat ranges or something?

[DAEDALUS]

The 5B is a hot plug; the 6B is standard.

[1992Q45A]

Hot plug being better in heat?

[DAEDALUS]

Hot plug being hotter.

The length of the ceramic insulator before it contacts the metal of the plug. How fast it transmits the heat of combustion to the heads..........average plug tip temperature......too Cold and it may foul at idle, too Hot and it may set off preignition at sustained high rpms.For most idle fouling is the worst case since few drive at high rpm for a long time in Summer.

Plus or minus 1 heat range 5,6 or 7 won't affect power at all.

Guess the real criteria is how many times per day you exceed 5500 rpms regularly vs the more normal driver whose average day is 2,000 rpm [675>2,700 rpm].....can't go wrong with 6B

[1992Q45A]

So if you drive at WOT frequently the 5b is the best?

[DAEDALUS]

No...at WOT you don't need help keeping the plugs hot. Short commutes in Anchorage, maybe.

[1992Q45A]

Which one of the three available, are the best for driving it like you stole it driving?

[elwesso]

For the 90-93 the 6B were stock, in the 94 the 5B were standard..

6B would probably be best if its all WOT and highway drivings (no short trips), but overall if the person doesnt know, I always recommend the 5B, cant go wrong with those.....
