Best price we have found for this plug and we go through 2-3 standard NGK to one of these over a long race weekend so these actually save us money and wrench time.
Scott Reed (store manager) –
We have run into a lean running situation when racing and a standard plug has given us a DNF in the past and these high temp iridium plugs allowed us to finish a race and retune the carb.
