No mainstream parts catalog I have ever seen has consistent, accurate information for Ferrari and all should be relied on only with great caution.
Nah has an HX series of Ruthenium spark plugs. Anyone know if these are an upgrade available for our cars?
It is an element very similar to Platinum. It is being used to survive longer in very modern engines with very lean and very hot mixtures. Has zero benefit in a 308/328. No harm to use them but no reason to pay extra for them either.
I still use the Champion N7YC (813). They cost about .99 cents ea. I usually replace them at every major service. There are lot's of places to spend money on these cars. Note-I have a turbo, so fine wire or other plugs aren't a good mix for me.
Ferrari used Champion plugs into the late 90's. We replaced thousands of them under warranty for running complaints until Ferrari finally got smart in about 99 and started using NGK's. We got the Champions out and good plugs installed ASAP as far back as the late 70's.
