E3 Racing Plugs

When I still had my shop open, I pulled more new, but misfiring, E3 and Split Fire spark plugs than all others combined. I avoid that stuff like the plague. Ditto NGK. I know guys that use the latter with good results, but we had to replace too many just installed during recent tune ups for me to trust them. We were doing 10 to 12 tune ups a day, some of it diagnosing and fixing problems from DIY guys and other shops. I have seen fewer issues with Autolite spark plugs than any other.
