Any of the pelican-parts recommended spark plugs are good, which include bosch 4-tip and NGK 2-tip and Beru Ultra 2-tip (like what were in mine).

I was impressed by the NGK quality of construction. Instead of the threads going into a flat sealed area with an aluminum crush ring, they went into a tapered cone with a very nice tapered & thick crush washer.

Whether or not this makes a damn bit of difference in regular use, probably not, but I'm guessing the strength of the seal is enhanced because of it.
