Does anyone remember if this was a problem? I have since fouled out 2 sets of plugs in different cylinders. Is there a better replacement plug than the NGK IR KL8Ai plug? The 1st time I replaced with a compatible Champion plug, but looks lean compared to the NGK's that were stock? But hasn't fouled out.Any options out there if you remember? It is the wife's sled which is like new.I just replaced all with the Champion plugs? Any other options would be appreciated Thanks Mike
