I went through the trouble to take off the spark plug of my buddies KFX450 to swap it out for an Iridium. Advance Auto doesn't have anything Iridium or NGK for the KFX450R or the KX450F in their little computer. I was wondering if anybody has went through the trouble to get an Iridium plug. If so, what is the part number? Or are they even available for it yet?
