    Vintage OEM Ferrari spark plugs

    It seems Champion N7YC are tough to source out in Ontario, Canada where I live. All the parts suppliers wanted to do is give me a crossover part. My 4 carburetor ‘78 Ferrari 308 runs best with Champions, as others foul too easily. Also, those are the ones Enzo wanted in his cars. Cheers
