So many choices for a spark plug application for my beloved B230FT.
Standard, titanium, platinum, iridium, nuclear, silver & gold plated, and so on.
I've not had good service out of standard Volvo OEM plugs. That said, and with no real consideration for cost, what is the best overall choice of spark plug for this freshly rebuilt red block turbo engine?
Out here on the Left Coast, so it gets hot more often than not, so please consider heat range with your opinion.
Winner of the debate gets my personal and sincere best wishes.
Let the cards and letter commence!
Thank you.
