E-3 plugs worth the money?

All these multiple electrode plugs are snake oil. Every. Single. One. The EPA puts tremendous pressure on the US automakers to make cars get better and better mileage and have cleaner and cleaner emissions every year. As said, if claims these type plugs did anything they claimed, they would be OE plugs in every US vehicle on the market. They're not.

The ones I love are the guys that come in and demand one type plug over another saying anything else is junk. There aren't but three or four spark plug factories in the world. Think about that for a minute. That means chances are that the same company that makes your precious NGK plugs also makes the Champion "lawn mower plugs" you cannot stand.

I have run Champion plugs almost exclusively in my Mopars over the years and have had great success with them, yet I always hear and see people run them down. They are good plugs and I say that from first hand, personal experience.

Lastly, consider this. How many spark plugs do you think are made world wide every year? Isn't it possible for some bad batches to get out? Just like has been said of the NGK plugs in this thread. Lots of people have a hard on for them. I never have used them. I am sure they are a good plug. I have always preferred something else.

AC plugs for any GM products I've owned. I run Autolite or Motorcraft in our Fords now and I have always used Champions in Mopars. Got a fresh set of Champions in my Hemi sittin on the floor now.

In the end a spark plug is pretty much a spark plug. All it can do is spark. That's pretty difficult to improve upon.

Lastly, I will include this. The best conductor in the world is copper. Any other metal conducts electricity at a little less rate. That means when you jump up to those "better" platinum plugs, you are not getting as good of a conductor. It's true, look it up for yourself.

The further away you get from copper with nickle, platinum, double platinum and iridium, the less you are conducting spark. The only advantage to those other plugs is that they last longer. That's a fact, no matter how much you want to believe the marketing hype that surrounds spark plugs.

Some may say arguing about conductivity of different metals is splitting hairs and I agree, maybe it is. But the fact is that those other type metal plugs offer absolutely zero better and a little less conductivity than a good old copper core plug.

That said, I will admit I do have Autolite platinum plugs in my 75 F250, simply because I got them on Ebay new for 25 cents a piece SHIPPED when I needed a tune up. lol
