Spark plugs
 

I posted a topic last week as to the most popular spark plug used on a 1980 3.0 SC.

I have spent ages again looking at comparison charts, and I keep getting different rccommendations. I could do with a concensus from other owners.

Presently mine has W3C, and I have a slight misfire, I wonder whether it is because they are too cold. New leads fitted.

Thanks

Try a new distro cap and rotor as well as new plugs it may help with the misfire. I dont remember what I run but plugs are relatively cheap you could run a set for a month see how they work then change to another type for a test.
