I was watching horsepower TV this weekend and they did a dyno test on E3 spark plugs and another high end set of plugs. The E3 plugs made 5 more HP and used less fuel. I thought this was interested and looked up E3 online to see if they sold plugs for my stang and they do not. I looked at there catalog and they sell plugs for the S197 V6 and the 5.4 ltr engines. I also checked the Explorer and Expedition - no 4.6 ltr plugs for the 281. What is up with that? They seem like really good plugs. Are they in development or what?

Here is a link to e3's website and a video clip of the dyno pull from HP TV. They also show a comparison of the two plugs spark and it is impressive how much better the spark is on the E3 plugs. I want a set now! http://www.e3sparkplugs.com/

I just dropped them an email, I'll post there their reply...

 

I have no experience with them in automobiles but, I use them in my lawn mower and weed eater and they always start on the first pull and seem to go further on a tank of fuel.

 

ford made a weird plug design for the s197 most plugs can be used for many different cars so it is cost effective to make but for got weird and made an odd design

 

Those plugs may in fact be a good product, but I don't trust the endorsements of those TV shows. Some of the products they rave about seem to be questionable (Z-Max, the electrostatic rust preventer, etc.).

 

Amen!

caveat emptor

 

our plugs are the same as the 5.4 L ones arent they??
