E3 Spark Plugs–Not such a good idea


So I was in one of my favorite auto parts stores and looking for spark plugs for my Toyota pickup truck.  It’s a 1992 red mini-pickup with the 22RE 2.4 liter, four cylinder engine.  They guy at the counter asks me what kind of spark plug I am looking for.  I told him that I wanted the best he had.  He has a set of E3 spark plugs which he claims are the ultimate spark plug.  OK, I’ll give them a try.  Less than 6000 miles later I am on the highway and the engine is having high rpm misfires.  This is bad.  So I pull off and hit another auto parts store.

I pull the spark plugs right there in the parking lot and look what I find.  These things are junk.  The electrode has so shrouded the spark that deposits are caked on and have raised the resistance so high that the plugs misfire.


I don’t think I’ll be using E3 spark plugs any time soon.

  1. The guy at my local store suggested the same plugs the last time I was tuning up my VW. Auto store employes are often pressured into selling certain brands and it changes monthly. I’m sure this month they have a new best brand!

    I’m surprised you didn’t opt for OEM from the get-go?

    Keep it simple. Good ole cheap NGKs or Champpions are the way to go.

    e3s are the best there is i dont work at a part store or anything i just know off of mechanics and race car drivers thats what they say to use cause it makes the strongest spark and gives you most power and fuel efficiency also the reason more than likely it didnt work is cause your engine needs new heads or a compression check cause if it cant handle those spark plugs there is something wrong with the engine its self

  6. I had an issue with misfires and E3 plugs recently as well. First set I tried burned the electrodes down to nubs and so the company sent me another set after I wrote them a letter. This time #1 cylinder starts misfiring. I change the older but still in perfect shape 10 mm wires and it still misfires. I put an old set of AC plugs I had lying around and the thing now runs perfect? I’m confused?
