This type of spark plug has a copper core to allow for large heat variances. The tip of the spark plug is a nickel alloy which allows for a extended life span. The body of the spark plug is a high alumina ceramic. This kind of shell allows for good insulation and heat dissipation.


The spark plug gap for this kind of ATV is .035. If you want to check the gap on your spark plugs, use a gap tool.


When you are installing a spark plug in your Rancher, make sure to use caution. Over-tightening a spark plug can seriously damage your spark plug or engine. Do not use more than 6 foot-pounds of torque when tightening the plug into place. Tighten until snug, that is it.
