Amazon.com ngk standard 5129 $4.12 iridium 7803 $7.40 difference $3.28 . Can you afford to take the chance ? Good luck .
juice... not an issue affording it but i'm talking about a low hp, non performance scooter here.
got this to battle $4+ gas period.
my etailer has oem's for a buck n change.
since this is my first scooter of any kind, I have zero frame of reference.
just not one to throw dollars at something cause it's new and expensive so must be better.
