Davidson motorcycles. The patented DiamondFIRE
ground electrode is secured to the shell with two legs
to help facilitate heat transfer, and to withstand the
intense vibration of powersport engine applications.
The unique DiamondFIRE side wire is proven to
increase power, reduce fuel consumption and
improve hydrocarbon emissions in long-term use.
