Anyone using E3 spark plugs in their 302? I have autolite plugs in my 73 and it's time to change them out. Was thinking about going with the E3's. What would be the correct one's for mine? Thanks.
When using std points ign, just about any new plug will perform better than one that's run 12-15K mi. I've never tried E3 but eons ago tried some with double electrodes. Like any new plug, ran better for maybe two months, at that point no perceptible difference from stock plug.
