Traditional spark plugs, Premium, Super, Regular, High Perfermance, Splitfire, Platinum, Iridium.
"These are one step colder" colder then THAT MEAN WHAT ?
"These are for track use or high output motors" - Is that high reves. ?
I have used Bosch and NGK for years now. I do a cross reference for X5DC and get - Denso,Splitfire,Autolite,Champion,NGK,Sino.
If one spark is good, why do I need two to three sparks. Or even Iridium ?
