What modern spark plug would be the equivalent for the Flea. I've cross referenced it on a couple of different sites and came up with two cross ref's NGK BH6S and B4H or the Champion L86C ,so not sure as to which one would be correct/better .
I much prefer the Champion L86C over NGK. But I've just completed well over 400 miles in France on my M20 with a Bosch W8AC fitted and I think I'll stick with Bosch for the time being. Ron
