Greetings Fellow Ferrari Owners.
I was wondring if other owners have a problem with spark plugs fouling or failing on the carb models? I run on NGK B8ES, but they seem to be a touch weak? Has anyone run a hotter plug in their cars to solve this? Bear in mind I live in a warm climate..
Any Thoughts ?:nerd:

Those plugs are too cold. Recommended plug for the 308 is the BPR7ES or the iridium equivalent, the BPR7EIX. If I were you, I would put the iridium plugs in her. They have proven to be much cleaner firing and less susceptible to fouling. I have iridium plugs in my 575M.

Agree on the plug types. Depending on how you drive, maybe go hotter? (imho: I don't think climate has a big effect on combustion chamber temp's) I too mostly run 7's. I've had good luck w NGK in the 6 range. I'd expect 8 to have trouble anywhere but the track. Also, the fine wire plugs seem happier w carbs.
