As many of you may have seen from the post below, I bought a service pack of Champion plugs for my JD 425 and some other tractors my neighbors have that use the same plug. Well, they weren't something I'd put in one of my engines, so they went back.

Well, after some searching, and checking advise, I found many, many recommendations to use japanese plugs in japanese engines, and american plugs in US engines, ie NGK in Kawasaki and Champion in B&S. There were all kinds of horror stories that brand X plug caused my engine to sputter, stall and blow up!
So, being one who likes to check out things for myself and my underlying belief that for the vast majority of applications, "plugs is plugs", I blasphemed and put Autolite Iridium plugs in my Kawasaki water cooled engine. Guess what, no difference whatsoever, ran fine, started fine, stopped fine, had great power, mowed like a champ. I would have never known the difference had I not done the switch myself. I mow about 5 acres of rough ground every week, and have done two mowings now with the Autolite plugs, before that NGK for several mowings.
What have you all found about plugs for small to medium tractors?
