I tried to do a search but the search engine does not accept "E3" as a word and I had no luck finding them under "spark plugs". I saw them using them as upgrades on one of the Horsepower shows on Spike TV. They dyno trested them at some huge numbers so I was wondering if they were tried out by anyone here in their 5.4 F150's? I'm no motor head but if I can get better gas mileage and horsepower then I'd like to give it a shot.

 

here is a link to their site.......http://www.e3sparkplugs.com/technology.htm

 

Nobody makes plugs for the 5.4 3V besides Motorcraft/Autolite, Brisk, Denso, and Champion.

 

they are not available for our trucks. the 2004-up uses a different desighn of spark plug.

 

thanks for the info, that kills that idea.
