Interesting, I was looking at the same thing last night. I went to the ngk website and got nothing as far as the coil is concerned. I think the seller (as stated before) just put the ngk wire on the stock coil. Amazon sells the same coil for a little less ngk # 8048(with free shipping if you have amazon prime). HTH, Lyle
PS: I just bought 2 of them, one for the monster moto and another for a sears drover (recently purchased). Both have 212cc predators installed. I'm building another bike, started today on that.:thumbsup::biggrin:
