Here's a close-up pic of my spark plugs (both look the same) after about 6k miles with the Xied's. I have a stage I intake and SE slip-on's. I think they look OK but I'm far from a trained mechanic. Tell me what you think.

 

Heres a Link that may help .. FWIW they look good to me ...

Looks good to me, I'm starting to like these things more and more.

 

Light grey,looking good.

 

Thanks for the link JayStronghawk. I do think the Xied's are a great product.

 

A year ago almost to the day I installed the Xied's. The plug in the first picture was taken the day of the install. The second shot was taken today, a year later, with a full season of riding. For me about 4000 miles. I've been pretty pleased, I think they are doing just what I expected them to do.

 

Pagan they look very good to me, I'll be servicing my 48 in the next month or so having done approximately 3,000 miles since fitting the XiED's and I hope mine look as good as yours!

I will report back
